You could compare this game to Halo, which I have also played on the PC and XBOX and I actually enjoyed this more. Pariah while not groundbreaking is fun and to complete was challenging just to the right degree. The cons are that the environments don't seem to differ a huge amount and for 3 discs of installment wasn't that long an adventure. There is nothing extraordinary here but I do think if you are an FPS fan it's worth a shot.
