im thinking about getting dokuro... but I don't think I would get to it any time soon so I will likely just hold off until it's likely added to plus sometime next year or so.
I need to get around to playing tekken. I am not big into fighters but I don't mind playing them for time to time. I absolutely detest street fighter 4 though, to hardcore for me or something
The fighters I enjoy tend to be simpler ones, Soul Cal (2-4), Blazblue (on stylish

) Smash Bros (yes it's a fighter, a party fighter but still a fighter damn it), and random anime fighting games that are easily abuseable and mostly only fun because I like DBZ more than I should given it's quality lol.
I didn't mind my time spent with King of Fighters 13 either, but I wasn't a fan of virtual fighter that was given away with plus... it wasn't bad just not interesting for me.
In general I prefer playing extra modes in fighters instead of the vs in them. I spend most of my time on fighters in challenge towers or rpg like modes. I plan on picking up MK for the challenge towers and nothing more.
