Controversial StarForce Copy Protection Creators Quizzed
... this is a pretty interesting point. Cedega (formerly WineX) does not have support for most of the new copy protection mechanisms around, and mentions as much in their documentation. This means that you can install and run pirated games in Linux that you wouldn't be able to in Windows.
I mention this not to promote piracy, but because it raises an interesting legal point - Transgaming are technically selling a product that allows you to circumvent copy protection - granted, in a very broad sense. But I wonder how long they'll be allowed to proceed before getting smacked down under the new US laws designed to prevent this sort of thing.
