This is Rifts. A great diced RPG. Though diceless RPG's (there is only one I know of) are great, this one needs dice. It is a very detailed world. The authors at Pallidium spent alot of time on this on. One of the main problem I see is the cost. At about $10-$30(most are about $20), the books are expensive. However the only book that is nessesary is the fist-$26.95.
Here are what I have on rifts:
