I think your list is genius, except I'm not the biggest Bioshock fan.
It's really nice to see Metal Gear Rising on this list, too many people played DmC and passed up on MGR
I played DmC and passed on Revengeance because it's apparently only 4 hours long. I recently pre-ordered it on PC for $20, which seems like the right price for it. It's just a hard sell, coming off of DmC which is 10-15 hours.
You've been deceived. MGR is kinda short, but it's like 7-9 hours, not 4 hours. The "four hours" figure came from people running through the game on the easier difficulties, while the in-game timer only counts the successful gameplay runs between checkpoints. If you die or restart to get a better score, then all the time since the last checkpoint isn't counted, cutscenes aren't counted, and the really extensive optional Codec conversations might not be counted either.
