The future is now
ZBrush 3.1 is a cornerstone product that every high resolution and current-gen gaming artist needs to have. It has a few flaws (as every piece of software does) but right now it can't be topped for the shear number of creative things one can do with it. I find myself constantly returning to it for a wide range of uses beyond digital sculpture. MatCap, texture projecting, retopologizing... it's all right there waiting to be used in cool and unique ways. If you are on the fence then hop off and buy this product.
