Castle Crashers
(I'll give you that),
Alien Hominid
(doesn't count, on various other consoles (gamecube for one)),
Geomotry Wars: Retro Evolved (1&2)
(I think that might be on PC)
E
74 Error
(Fix'd But I've never heard of it),
Portal: Still Alive
(that was a complete rip off, it was a free PC add on pack by some fans!)
and Rez HD
(also on various other consoles I believe).
Then there's the less artsy stuff like Kingdom For Keflings and Death Tank. And 1 vs 100 coming later this year - along with The Secret Of Monkey Island and Turtles In Time.
(SoMI I'll give you, but 1 vs 100? Other than being a cool name, who cares about THAT?)
I know the last 3 in my list aren't out yet, but they will be by the end of the year. I doubt 1 vs 100 will make any sort of GOTY category, but I will be surprised if Monkey Island and Turtles in Time
don't make that category.
