User blog comment:J1coupe/Minecraft vs. Roblox. Epic Rap Battles of Video Games Season 3./@comment-5264252-20140106070744

Got a few suggestions, if you're interested, or even take them:

Kirby vs Ristar (battle of the stretchy star warriors. I've seen Kirby vs Pac-Man as both are big eaters, but I feel Ristar would be good for bringing in a real classic game.)

Phoenix Wright vs Professor Layton (don't think they really faced off in game, though I've never played it, so I'd love to see how they'd really do in battle, especially since both fight with words and evidence already in their games)

Pokémon vs Digimon or Digimon vs Tamagotchi (First is obvious, maybe Pikachu vs Agumon with others backing them up. Second being that Digimon was made as a boy-version of Tamagotchi. Yes, Digimon started as a game, for those that didn't know. The anime just popularized and built on it.)

Kidd Radd vs Wreck-It Ralph (Okay, teeeechnically, neither are video game characters, one is from a movie and the other is from a webcomic, but both are aware that they're video game characters and travel to various other games parodying real games. That works, right? ...no? ...okay.)
