Heh, yeah, they were very big on keeping the sys reqs down. The idea is that it should be playable on most standard netbooks (!) these days, which is cool and a testament to their ability to tweak their engine. Cause it may not look like Crysis, it sure has some colorful and good design choices.
I haven't played it enough to judge it though. Will get back at you with that.
It's gotten reviews in the 80-85% mark most of the time which is remarkable for a game like this...the underlying mechanics are brilliant and the lootfever is high. What more does anyone expect?
