Asura's Wrath is my favorite game of all time. Sure the game is immensely short even with the part 4 dlc and the 2 lost episodes and most of the time it's in cutscene/ QTE mode, but the unique thing about the game is the fact it's more story based than gameplay unlike most hack & slash and beat em ups. Also the fights were epic! What other game has a first boss the size of the Earth and you kill him by punching his finger! And he's the weakest of the demigod bosses. Heck, you fight Ryu and Akuma from Street Fighter, one of the first fighting games. The only thing that could make this better is dlc against Goku, Dante (Devil May Cry), Amaterasu (Okami), Viewtiful Joe (Viewtiful Joe), and Megaman (Old school Megaman or Megaman X) and i'll die happy.
Honorable mentions
Okami
Resident Evil 4
Ultimate MvC 3 (Dante, Vergil, Frank West, Amaterasu, Nemesis, Strider Hiryu, Deapool, Dormannu and Ghost Rider)
Walking Dead (not Survival Instinct)
( as you can see from my name and the list, I love Capcom games)
