MVC3 its out of contest...DS2 su*cks! its another cheap ocmmercial attempt...no heart content, no soul, no thaught...its just hollowing game without any charm at alll...while MVC3 definitely has it all!
The third game in a series that has Marvel and Capcom assets to attract comic book and fighter fans isn't commercial? Be realistic here. MVC3 is even based on the TVC engine for more mainstream appeal.
DS2 is pretty much the complete opposite of what you just said, bad marketing campaign aside (I've completed the game). It's the current gen's best survival horror game without a doubt. It does lack replay value compared to a fighter though.
