I'd like to start a discussion around collecting-based games, with the following prompt question:

What non-card-based alternatives to TCG/CCGs exist which satisfy the same criteria?

This "criteria" is my understanding of what makes TCGs/CCGs appealing, and includes but is not limited to:

• collectible/tradable (not necessarily monetized),
• portable/relatively self-contained (this could include apps, handheld consoles),
• the constant drive to expand the collection (whether it's through the randomness of distribution not ensuring particular collectibles, or an appealing reward system like in the Pokemon games).

I wish to divorce these criteria from the card format. Of course, the list of criteria not extensive and I am actively seeking a deeper understanding of what makes these card-based games so appealing. Discussions on the nature of gambling-addiction and the impact of secondary market values also very welcome.

The best example I can think of is the Pokemon games for handheld consoles. These games pre-dated the Pokemon card game and are a great example of the appeal of card games existing and thriving in a non-card format (which ironically led to the card game adaptation).

Another is Warhammer and the tabletop wargaming family. This is interesting to me but really seems to be in a completely different ballpark because it lacks agility and thus is far less appealing to many players.

Note: my reference point to what makes games like these appealing" is very biased by card games, specifically the current "big three" of TCG/CCGs: Magic: the Gathering, Pokemon, and YuGiOh. I'd appreciate suggestions of other relatively successful or simply well-designed games which employ collectibility as a core mechanic. They don't even have to be portable, as long as you're clear about that.

tl;dr: let's talk about alternatives to card games which depend on collecting as a core mechanic

Edit: formatting.

I've been out of the MTG scene for a while but I'm going to try to follow today in the background while I work. I'm really interested in how things go with the PT pushed back a few weeks from release, it doesn't sound like we're expecting any breakout decks to pop up. It should be starting right about now, the stream is available on Twitch.
