I just got my copy of SR4 two days ago, and I am completely blown away.

The new system is great. SR3 fried my brain. This one is simple and easy to grasp. It also seems complete. I don't feel the need to buy a ton of core books just to be able to play the game. And thank heavens there are rules for falling and critters in the core book!

The wireless matrix is fantastic. It seems like you took the best part out of the worst setting in Ex Machina and turned it into something playable. The setting just flows out of the rules, and I kept getting ideas for games all the way through it.

Absolutely brilliant.
