Guacamelee and metroid prime trilogy...would be neat to see guacamelee reimagined as a first person adventure. Of course guacamelee is already borrowing heavily from the metroid series, so it would be interesting to see how that would look with a prime feel added...oh wait, maybe that's what next level games were going for with that ugly artwork for the 3DS. Ha.

I think he means Persona 3 and Persona 4. So he said it already happened.

The four games Ive neen currently playing are Project X Zone, Pokemon shuffle, Rome 2 Toal War, and Windwaker hd. Good luck lol.

Gta 5 and hitman 2. Wow that would be the best game ever.

Uncharted 3: Drake's Deception and Godzilla: Destroy All Monsters Melee? Poor poor Nathan, watcha gonna do? There's no hope for you, hey watcha gonna do?

Madden 15 and Titanfall..... nope don't go together at all

DmC meets Olli Olli 2... fuck yeah!!
Combine DmC combat while riding a skateboard OlliOlli style =D

Grand Theft Auto V and Dead Rising 2: the wish of many fans come true.

Roller Coaster Tycoon and Civ V.

That would be a pain in the ass. Wait multiple millenniums to FINALLY build a theme park? No thank you.

Although launching Ghandi off a roller coaster would be guilty fun.... maybe it would be worth it.

The last two games are direct sequels of each other. Pretty sure that doesn't count.
I don't know how I should approach this, really.

edit: Oh, last two PC games I've played.  Besiege and Prop Hunt.  That would be funny.
