I'm a huge boxing fan, and even train it myself, so I've been in the search of a good boxing game for some time. This game is still in early access, and I definitely see some potential, but right now is not worth buying. The way it is right now, it gets really repetiting and boring after a couple of hours. Without the addition of a career mode that makes the single player experience more fun, all the game is a boxing fight simulator, and personally that's not what I'm looking for.
Like I said, I do see the potential for a great sports game here, and wish to see it accomplished, but I wouldn't recommend buying it right now.
