Half-Life, Half-Life 2, Bioshock at 96. That's as high as it gets, as I don't play *cou*puny*gh* console games.
Eufloria 63. Maybe. Had to plow through so many pages that I might've skipped the lowest. I'm very surprised at the result. It's one of the best, if not the very best ambient game. Steam clock says I've spent 27 enjoyable hours with it. Mostly listening to music, just chilling, as you do with these kind of games. The written review pieces also seem to hold it at higher value than the accompanying scores. Although, there was a huge patch, maybe a year ago, that changed it drastically. And that actually destroyed the great calm atmosphere as well as it did balance some stuff.
