If you could make one game by combining any two games of any franchise, what games would you combine and what would this combination be like in terms of gameplay?
Mario Galaxy and Fallout 3. 
Final Fantasy & Assassins Creed. I would love to explore the cities in FF games more thoroughly.
Persona 4 and Dark Souls a very interactive rpg with realistic fighting and mystery like Dark Souls.
Well, uncomming Valiant Hearts: The Great War is like The Cave with the art style of Valkyria Chronicles. A match made in heaven in my mind.
Tekken 3 and Final Fantasy VI. Basically FFVI but when you fight it's an acutal fight!
Pokemon and Skyrim. Give me a world as huge as Skyrim which has every single Pokemon somewhere to find, gyms to discover (not a part of the main quest, something you discover) and just all those Bethesda secrets with Pokemon's universe and critters to give something even more interesting.
Animal Crossing and Namco Museum.
I would love to see Skyrim meets TellTale's The Walking Dead. I'd love to see Kirkman's zombie universe as a sprawling, massively explorable world which offers lots of variety in consequence due to the player's actions. I even wrote a blog about it, awhile back!
EA's Black and Halo 4. Guns would be the stars and environments would be totaly destroyable. Adding that with the enemy AI of halo would make a great FPS that would quench my bloodlust.
What? stop looking at me like that!
