It was a really rocky start. I've never had a tutorial treat me like a fool before (it repeated itself so many times it felt like I was watching some meandering children's "educational" show) and it was very slow going at the beginning. I understand the importance of tutorials and really don't mind them at all, but please don't condescend to me you know? I got it the first time.
With that and the opening in general not being much fun, the game bored me enough that I took a couple days away from it, and had to force myself to play tonight.
However, once the game opened up and finally let me play around a bit, including the practice mode, I've finally learned how the experience system works, and I've gotta say this game is fun! Now, I had to force myself to stop.
Maybe the practice fights do break the game (I've just begun and its already noticeable
I'm still very early on, because practicing has slowed me down a good deal, but I'm really looking forward to the rest of this game. Fun stuff.
