I was wondering if anybody had any tips for muscling through a game. I've got a few games I want to play or go back to, such as Stardew Valley (I completed it before the 1.3 update, wanna play 1.4), and Factorio (I bought in a fit of passion, haven't gotten an hour in). There are others, but these are the two I find myself going "I'm going to play this!" and I just never get to, and it's not for time.

I like the concepts of these games, and I've got something like 135 hours on Stardew Valley, but seem to get bored after I've restarted it (I lost some key items and bugs caused me to never get them back, plus the mine completion bug fixed in 1.3). I started Slime Rancher after playing through it in early access, but can't seem to get back into it after it went gold a couple years ago.

I realize I'm sort of asking for a way to force myself to play games, but has anybody done this? I'm thinking for a given game I can set smaller goals to strive for, and work on doing that, but was wondering if anybody has any ideas.

What have you been listening to this week? You don't need to do a 6000 word review if you don't want to, but please write something! If you've just picked up some music, please update on that as well, we'd love to see your hauls :)

Feel free to give recs or discuss anything about each others' listening habits.

You can make a chart if you use last.fm:

As previously discussed here, Humble Monthly is switching to a new model with no "mystery games" where you'll be able to choose which ones you want to keep from a set selection.

It looks like the games were inadvertently revealed already (image link), so the first month's options will probably be:

• Shadow of the Tomb Raider
• Blasphemous
• Void Bastards
• Phantom Doctrine
• Dead In Vinland
• Horizon Chase Turbo
• Dark Future: Blood Red States
• Desert Child
• Aegis Defenders
• X-Morph: Defense

If that's an interesting set of games to you, you'll probably want to subscribe to Humble Monthly now to be grandfathered in on the "Classic" plan, which will let you keep all 10 games every month for $12/month (and you should be able to "pause" if you don't like a particular month). Otherwise, the plan options that will be available after Dec 6 are more expensive for fewer choices.
