It's a decent mx game. People hate it due to the pricing model. It comes with less content if you buy the base game, but the game is also priced way lower then most new games. You can pick this up for 20 bucks, get all the dlc, and still be less then 50 dollars in. Most new games launch at 60 or 70 and stay there for years now. I personally prefer this model but I am one of the minority apparently.
As for the graphics, they aren't amazing, but they are better then any other mx vs atv game. The career is still not that deep, but at least they tried in this. Physics are a little weird at times. You will wreck when you think you shouldn't have and your body will ragdoll, it's less forgiving then a lot of the older games. It feels decent though overall once you get used to it. It's a bit less arcady then all out, while still not being simulation like.
Personally I think it's a pretty solid game. The content is there, has at least somewhat of a progression system, it's a good time for what you pay. People need to get over the ps2 era of games.
