As a big fan of local multiplayer games, I originally got this thinking it'd be a fun couple hours of casual fighting with a group of friends. While it was certainly that, I never expected to get so deep into (what I deemed as) a "party game."
The online community is fantastically rich- Just hop in the group chat, and you're bound to find a match with someone of whatever skill you're looking for, or someone to help practice a specific tactic, or just some casual FFA fun. There are tournaments hosted every weekend, and virtually everyone in the community is a blast to talk to.
But the game itself has a depth I have never seen before- I have over 100 hours logged of high-skill matches and tournaments, and I am still finding new strategies and mechanics to use. My current repertoire is even missing two mechanics that I know, and with those two, there are plenty of uses I haven't even thought of.
The depth is incredible. The community is great. The style is fantastic, and the play is like nothing I've seen before. Buy the game- You won't be disappointed.
