I have also been seriously considering buying urw, there are a couple of things that hold me back.
The first is I have not actually bought any software for about 18 years, I usually stick with FOSS as the projects develop better with a team of occasional contributers and I feel more comfortable if I can add code, graphics or whatever.
Another thing holding me back is steam, basically I do not trust any faceless multinational corporation with my data, it also seams that to use the steam version on linux I must also install and run their OS, that is never going to happen.
