Er, yeah. That's kinda the point of the thread, isn't it?
I wouldn't get too hung up about it. Two stars is a game that has some redeeming features that some people might enjoy. Three stars is an above average (i.e. good) game that I like and is worth playing and which I recommend. So don't worry, I like MUSHA! It's just that it's pretty easy and the vast majority of your score comes once you beat the final boss, thus rendering scoring a bit pointless. Look at the playthrough:

Score at 37 minutes (the end) - 130 million
