If your games library disappeared, which games would you repurchase?

Zero. I would dedrm what I had on disk and could since I paid for it already, be sad about the rest and be significantly less likely to bother "purchasing" files containing drm.

But hypotetically games from indie developers that could presumably use the support:

• Creeper World series
• Titan Outpost
• Colony Ship
• Defender's Quest 2 (assuming it gets released and does not dissapoint)
• and probably others

• Halo: Combat Evolved: I bought it for Xbox and a second copy for LANs, then again for the Anniversary in 2011, then MCC in 2014, then MCC in 2019. So what's one more time?
• The Elder Scrolls III: Morrowind: I have also bought this for Xbox, then later on GoG, and then again on Xbox One Backwards Compatibility, for the nostalgia, but OpenMW is the future.
• The Chronicles of Riddick: Escape from Butcher Bay: A third one I got on Xbox, then again in Assault on Dark Athena for 360, and finally on GoG over a decade ago when it was still available.
• Tom Clancy's Splinter Cell: I know, I know, there's a theme here, but it was such a great experience on Xbox that I couldn't help but buy it again on GoG.
• Metal Gear Solid 2: I bought Substance back in the day for—you guessed it—Xbox, then I bought it again in the HD Collection, and once more when it came to GoG, but now I just use RPCS3 to emulate.
• Tony Hawk's Pro Skater 2: I bought it for Xbox (starting to sound old). When I had a PSP, I used to play a homebrewed rip of it on the go. Now I emulate it on Xemu.
• Half-Life: I fell deeply in love with this game and it's expansion packs. Of all the games on this list, it's the only one that I purchased just once, because my Platinum Pack CD keys were redeemable on Steam. Now I play through Xash3D FWGS.
• Quake: I bought it on CD in the early 'oughts, then later on GoG through a sale. I'd buy it again in a heartbeat! Addicted to the sound of that Ironwail!
• Star Wars: Shadows of the Empire: I had it on N64, then bought a copy on GoG when it arrived there. I'm hoping this game gets some good decompilation treatment as I'd love to play it with a controller again.
• The Legend of Zelda: Ocarina of Time: Everybody remembers their first love, right? I bought the gold cart for N64, then when it came to 3DS some fourteen years ago, I bought one just to play it on the go. No regrets. If I had to buy it again just to play on Ship of Harkinian, I would.

In light of this, it may come as little surprise that I also enjoy watching reruns, lol!

I already paid for all of this, so I'd pirate everything that's not DRM-free on GOG or humble, and procure all the installers for everything else (I do keep an external hard drive with the installers of DRM-free games).

If you're asking to learn what I "still play"/has replay value, there's little I'd need in the short term (that costs money), and therefore little I'd have to pirate immediately. Beat Saber is one, Tabletop Simulator another, maybe Age of Empires 2. The Binding of Isaac: Rebirth? Some simulators, like Cities:Skylines? Stuff like that.

Answering for my kids (whose happiness is my happiness):

Geometry Dash
Celeste
Minecraft Java
Portal
Portal 2
Cookie Clicker (the one I don't enjoy)

Dark Souls
Dark Souls 2
Dark Souls 3
Bloodborne
Elden Ring
Monster Hunter 4U
Monster Hunter Generations Ultimate
Monster Hunter Rise
Monster Hunter World
Minecraft

That's it, that's all I'd need.

I think I would just re-buy whenever I felt a strong desire to play one of them. There are a lot of games in my digital library that I love, and like the feeling of "owning" even if I don't play regularly, but I don't think I would immediately re-buy those games "without hesitation" if they were lost.

So... probably Slay the Spire, Balatro, or Celeste would be the first one I'd get a craving for. Someone mentioned Halo MCC which I think would be another strong candidate, however it has been quite a while since I booted that one up. Along the same lines, maybe Duck Game.

• Minecraft, even though I haven't played in over a year.
• Hitman World of Assassination
• Rimworld
• Satisfactory
• Banished
• Timberborn
• FFXIV (all expansions)
• Eve Online, even though the client is free and I haven't played in a year.
• Planetside 2, even though the client is free and haven't played in over a year.
• Stellaris
• Final Fantasy XII, even though I have the original PS2 version, a Switch release, the PS4 release...
• And a few other JRPGs that I haven't yet finished/started, which is a long list.

Think that's where I'd start.

• Factorio
• Monster Hunter: World (Probably replace with Wilds after that comes out)
• Kerbal Space Program
• Stellaris
• Helldivers 2

Not much, just games that I feel comfort playing. Now if we add on to my Switch, then we have:

• Balatro
• Slay the Spire
• Pokemon (Pearl, Sword, Violet, in whatever order I feel like playing them again)

PS5?

• Armored Core 6

Probably just Total War Warhammer 3, because then I would have to buy all of the other games and DLC again to have everything. Small fortune, especially buying it all at once.

I have over 990 hours in as well as over 426 hours in the second game.

I would want to get other games back eventually, or just pirate them. But the amount I have played these games... I guess I have a problem.

Assuming you're only asking for digital games:

• Dark Souls 1
• Dark Souls 3
• Doom64
• Elden Ring
• Half-Life 2
• Metal Gear Rising¹
• Nier Replicant ver sqrt(1.5)
• SimCity4 Deluxe
• Yakuza 0

1: I have a physical copy for xbox, but I would prefer playing it on PC.

If I lost all access to my games libraries, I’d probably would revisit a lot of games through YouTube. I don’t actually play that many games anymore. More fun setting them up in my opinion.

Probably just Ozymandius since I still play it sometimes.

• Rimworld
• Helldivers 2
• Nova Drift (Itano circus of missiles makes me happy)
• Project Zomboid (yep, I'm sold on this crazy crazy "game" now)
• Noita
• Valheim
• Murder Simulator^H^H^HBlade & Sorcery
• Homeworld Remastered (because the mods are amazing)

Wow, that's a really good question!

Games I would love to have in no particulate order (and not taking in inspiration from others, so I'm intentionally "forgetting" some I wouldn't come up with myself):

• Jagged Alliance 2
• OpenTTD (this is free)
• Age of Empires 2
• Morrowind
• Final Fantasy X
• OG GTA San Andreas
• Gran Turismo 4 (if we count consoles)
• NFS Underground 2
• Half-Life 1
• Conflict: Freespace (Descent: Freespace in US)
• Zachtronics games (only puzzle/thinking ones)
• FTL: Faster than light and Into the breach

There are certainly others I would buy again, but these are the ones that immediately sprung into my mind.

Oh! How could I forgot Stardew Valley! And Talos Principle! I would buy those two immediately!

• The Binding of Isaac. The perfect roguelite IMO, I've been playing it on and off since the original flash game, and I'll probably still play it in 20 years, even though I'm not a good player.
• Dead Cells. Second best roguelite, but more skill-based.
• Diablo 3, on the Switch. Diablo 3 is perfect at what it offers. It's just dumb fun, and it works offline and couch-coop on consoles.
• Deep Rock Galactic. Probably the only multiplayer game I'd rebuy.
• Pokemon SoulSilver (Nintendo DS). Peak Pokémon, I have the original cartridge. Doubt I'll play it again but Pokémon Silver is a very high point in my childhood gaming memories, and the DS remake still feels modern enough today.
• Bloodborne (PS4). Probably won't ever launch it again either, but you can be sure I'll rebuy it in a heartbeat if a good port ever comes out on PC.

There are other games I'd rebuy later, but if I had to give a list "rebuy now!", this is it.
