Thanks for the recommendations! I've tried a few games over the past few days, but I'm not clicking with any of them.
So far I've tried: Anomaly Warzone, Anthill
On the list:
Hero Academy - looks interesting, but I don't that's what I'm really looking for.
Machinarium - I actually bought this a while ago, but never got around to playing it. I'll give it a go.
re: TinyCo - thanks for the recommendations, but I game up on sims with "The Sims" game came out in the early 2ks! Only because they are so addicting. So I usually skip sims now.
I think one of the biggest reasons I like KR is because it's easy to pick up and play, but not necessarily easy to win. And it's fun. Like I said, I'm still playing levels over and over looking for different ways to complete them. KR 2 can't come fast enough for me.
I played Fieldrunners a lot on my iPhone back when that first came out. Maybe I'll give that a go too.
