I've now completed "I Was a Teenage Exocolonist" multiple times. It's the sort of game where you kinda have to - I'm not going to spoil anything, but it's one of those games where your choices *really* matter.
Most of the characters are really well-written - even the terribly unlikable ones, in fact, are a compelling kind of unlikable. (With one exception - there's one character who just simply creeps me out, but I believe that's intentional). You end up wanting to get as many of them as you can - all of them, if possible! - to a good ending.
One thing that's very effective about the replay mechanic is that the game follows all its main characters from around age 10 to around age 20 - which makes it sort of heartbreaking when you've seen *bad* endings for the characters that the next time you loop around, you see sweet little innocent kids again, knowing what life has in store for them. At least for me, that makes me *want* to turn things around for the weird little exoplanet colony they live on.
It's both a good story about growing up, about choices and roads not taken, *and* a good piece of science fiction. It's probably one of the best game narrative experiences I've had this year.
