Timberborn sucked me in hard for about a week. I love watching the little beavers run around, and building hydro systems is a lot of fun! I sort of fell off trying some of the more difficult scenarios with the Iron Teeth. Dealing with harsher water conditions ends up being a lot slower and getting established become very repetitive and dull waiting for enough resources to come in to do anything. I hope they add more end-game options and challenges.

I also got really into Against the Storm, another city builder that also has beavers, but which is cleverly mixed with roguelike and boardgame elements to improve on replay value.
