Man.... I'm usually not one to gush about a port, but they did a really good job porting this! Steam isn't intrusive as it can typically be and keyboards and joysticks work right out of the box, no configuring needed. Although they haven't significantly improved the model quality, the texture quality, mapping and similar effects are far more detailed than they are on the 360 version, that is if you can run them. Even at the "lower" settings, it looks every bit as good as it did on the consoles.
So go buy this one. It's actually a good enough port to where I think I'll upgrade my arcade pc just for this.
