I'm in full 'retro mode' these days and am basically ignoring my PS3 and 360 in favor of emulated games via my PC and some stand alone PC offerings.
Currently playing via MAME:
2--Pac Man family of games
3--Nintendo family of single screen games (i.e. Donkey Kong, Donkey Kong Jr, Donkey Kong 3, Popeye, Original Mario Bros)
Via Kega Fusion (Sega 8 and 16 bit emulator)
1-- Shadow Dancer
2-- Golden Axe
3-- TMNT: Hyperstone Heist
4-- Ghouls n Ghosts
5-- NBA Jam
1-- Super Mario All Stars
2-- Donkey Kong Country
3-- Actraiser 2
Via Visual Boy Advance (Gameboy, Gameboy Color, Game Boy Advance)
1-- Double Dragon Advance
2-- Super Mario Advance (the one that plays a remix version of Super Mario USA)
3-- Gameboy versions of Batman the movie, Castlevania Adventure, and Tetris
Via Nestopia (NES emu)
1-- Contra, Super C and the very good rom hack found here, Revenge of Red Falcon
2-- Ghosts n Goblins
3-- Iron Tank
4-- Kung Fu
Via Magic Engine (TG16)
1-- Bomberman 93
2-- Supergrafx version of Ghouls n Ghosts
AS for non emulated games:
1-- Doom (via GZDoom) and some of the player mods floating around the internet
2-- Streets of Rage Remix. I have the final release version, V5.0, and it is just the ultimate in SOR action. So much so, it is hard to play the regular Genesis/MD versions again (unless someone comes up with cool hacks for some of those!)
3--Open BOR versions of beatem ups including fan versions of Final Fight, World Heroes (as a side scrolling brawler), and fan versions of Double Dragon.
Any and all of these games though, can change on a whim. I am known for binging on certain games or game types, then getting tired of them, then going on another binge of completely different types of games.
I suspect one of these days I will get back to playing my PS3 and 360 again...even though they have been overshadowed by PS4 and XBOne respectively...
