1. Rogue Legacy
The game looked like a lot of fun when I saw the quick look. Since Spelunky sort of already fits this niche, this game is lower on the list for now.
2. Retro City Rampage
I like the idea of this game, but I haven't gotten around to buying this one yet.
3. Zero Escape: Virtue's Last Reward
I finished 999, but I have a backlog. I really liked the game, though.
4. Muramasa: The Demon Blade
I heard that there was a Vita version coming. I can't decide if I want to play it or not. So many games...
I think I'd like this game, but there are so many others to play...
