Do you want a fighting game where you can screw around with your drunk friends on the weekends laughing at how dumb you guys look trying to fight each other, a la Sumotori Dreams? Then download this game.
Do you want a fighting simulator that you can get into immediately? Do you expect to look like the guys in that video up there right away? If you do, then don't download this game.
You'll get discouraged VERY quickly.
When they say you have total control, they mean it. You control every single muscle in your fighter's body. Are you expecting to know how to do a jump kick right away? Throw a punch? Expect to educate yourself on muscle movements instead, because trust me, you have no idea how complex even throwing a simple punch is.
I'm not kidding about learning muscle movements. You basically have to take an anatomy and physiology course before you can make your fighter even look human.
Go through the tutorial. It'll teach you some basics, but expect your fighter to look like a robot while fighting, and expect to get beat. A lot.
Then, watch some more advanced tutorials on Youtube. There are a surprising number of these, but for a game as complex as this, I'm not really that shocked. Even after practicing and watching Youtube videos, you'll still get beat, but don't get discouraged. There is a very high learning curve, but this is part of what makes this game exciting! I've played this game on and off for 7 years, and I'm still nowhere near as good as the higher ranked guys.
Playing this game takes commitment. It'll take a LONG time before your character will even make fluid movements. Don't expect to look like the guys in that video up there without years of practice. It'll take a long time, but is it worth it? You bet.
P.S. If you want to get serious and actually make your fighter look cool, be willing to spend a fortune because the shop is stupidly overpriced.
