Is it because of the gameplay? The character mash-ups? The possability of getting certain dlc characters? Why do you like this game? I know why I like this. I'm just curious of everyone else.
Besides Super Smash Bros. dominating the market, crossover fighters aren't really a huge broad genre. How many do we really have? Smash Bros, Street Fighter x Tekken (CAPCOM BLARGLE!), the SNK fighters, and can we count Anarchy Reigns(Max Anarchy) as well? When this was close to release, I wanted this both because it was a celebration of Playstation which I primarily grew up with, and it looked to be a promising Arena Brawler.
