Legit good. The negative I've encountered so far is performance issues- it takes a hit on large areas. Doesn't affect gameplay thankfully, but you can tell the framerate has dropped.
It's very much a RCR game in that it's not a straight beat-em-up and you will be running around town doing things. When you're walking around, you can choose to fight or run past enemies, although it's worth fighting since you level up and get money. You get new moves when you level up and you can also go to the dojo run by one of the Double Dragons and buy special moves. So the more you play, the more the attacks you can do opens up and it plays better as you go along.
If you want a straight beat-em-up, this is not your game, but I think most people would expect that from this.
