It's hard to recommend picking it up just yet because of the buggy state of the port, but it seems to be slowly fixing itself. Either way, waiting for rollback might be the best option.

It is still a great game though, shoddy port aside, and really brings me back to the era where some fighting games just did whatever kind of bullshit they wanted as far as mechanics and characters went. It's filled to the brim with depth (and cheese) and is a great time to sink your teeth and a few dozen hours into with friends. If you're in it for the single player experience you're probably better off just watching the story mode online or just reading about it, it's nothing special.
