New 3DS game revealed by Capcom! It's an action-shooter with the same world view as Lost Planet, but with anime-esque visuals. And it's made by... Kojima!! But, I thought he worked for Konami! What's going on here?! Just kidding, it's by someone who has the same last name, Shintaro Kojima, who worked on the Monster Hunter games... guess this is important after all. The game is called Ex Shooter and it's also coming out for the PS3.

PS3 and 3DS? What an odd combination. And no Vita or X360.

New Famitsu scans for Project X Zone are up. God, those anime girls... So... much... cleveage...

Ex shooter is sounding weird. Although I suppose we did get Ni No Kuni with a DS/PS3 combination. Interested to see more, although 'school-themed-story' doesn't sound promising, considering this is Japan we're talking about.

Project X-zone is becoming even more epic! So many characters and franchises, and those are the playable one only, imagine the amount of cameos, like ( <-- yours truly) Opa-Opa - it'll be a trip down memory lane!

High hopes for this game!

Even thought Mario is more known and will get higher in our lists, Pokemon games sell almost as good as 2D Marios and better than 3D Marios.

There are people that buy Nintendo consoles to play Mario games, but there are others that wants to play Pokemon games and that's what makes them buy Nintendo consoles.

At the end of the day, both games will make sales go up.

Project X Zone is a cross-over game by Capcom, Sega, and Namco Bandai. It's a spiritual successor to Namco X Capcom, a strategy-rpg game for the PS2. It's also being developed by Monolith Software.

Ex Shooter is the new 3DS, PS3 game by Capcom. Being produced by Shintaro Kojima, who worked on the Monster Hunter franchise. It's an action-shooter.
