I've used similar products in the past, with limited results. They're based on a technology called "Wine," which tricks the software into thinking the computer is a Windows machine. Works well for getting an old copy of Office to run on Mac or Linux, but since some code tweaking is needed, it doesn't get too useful for small software releases.
That being said, this one didn't have a trial when I previously saw it, so I'm willing to see how it does with RTS once I finish up a project and some midterms in the next week or two. Codeweavers has made decent apps in the past, so it's worth the try, at least.
