I've been replaying a lot of InFamous lately. Actually, just the first game and the second one's demo since I don't have anything else from the series. I really love the superhero origin story feeling it gives me and I noticed how my goals to become more powerful and save the city from chaos fit the theme so well. I also noticed some parallels with with Unicorn Training's goal of becoming strong enough to beat a looming threat.
The way it introduces new powers had me analyzing how when you're going through the game you'll find some aspect of combat or traversal cumbersome, then two missions later you get a power that makes that aspect a lot of fun and the game gains a rush of interest. You can really make a game feel new the whole way through by not showing all your offerings at once. I'll take that to heart when designing my own titles.
