This genre seems to be fairly popular, and I can see why. Instead of just building a deck for the sake of building it (like in Dominion), adding a racing element makes the game more interactive, tense, and tangible. I’ve only played a few, and I’m interested in how Heat compares to for example.
I really enjoy Clank! and The Quest for El Dorado. I’d say Quest is the better game. It’s cleaner, has fewer rules, and more variety in terms of maps. However, Clank! can be more fun. All the weird cards, the fights, drawing from the Dragon bag, and trying to get out alive make it a more lively (but also more random) game.
I love Clank in all its version. Even though I have not tried the Legacy version yet.
The Quest for El Dorado did not click with us, we thought its very similar to Clank but Clank is just better and much more fun.
We tried Heat at a meetup and found it interesting but ultimately not something we would add to our collection. Might also be related to the theme. I did find the mechanic of shifting gears and adding and removing heat from your deck interesting and at least on my first playthrough, difficult to manage.
