So Dissidia?
I was a huge Street Fighter nerd back in the day. SFII, III, and the Alpha series were my jam. I also played a bit of MK but quit at III because they removed all the guys I played (Reptile/Scorpion). I also got big into Guilty Gear in the early days but quit around the time of Access Core because I wasn't in love with some of the balancing changes and by then I met all my tournament grade friends who steamrolled me every time we played. I also played Soul Calibur 2, DOA2, and Tekken 2 back in the day, but I've never enjoyed 3D fighters as much.
I also tried to get into BlazBlue but just never got a feel for it. Same with SFIV. I need to give SFV another go, especially since a lot of characters I liked playing as are finally getting put back in.
I also played an unhealthy amount of Dissidia back in the day. I recently got the NT version and should probably check it out since I only played the demo and was a bit put off. I suck as SSB so please don't ask.
