> WINE was a thing for years and generally worked okay for a lot of things. Yes, but Valve's involvement handled "the last 10% takes the 90% of the time" part of WINE, and that's a great impact, IMHO. Trivia: I remember WINE guys laughing at WMF cursor exploit, then finding the exploit works on WINE too and fix it in panic, and then bragging bug-for-bug compatibility with Windows. It was hilarious. Also, WINE allowed Linux systems to be carrier for Windows USB flash drive virii without being affected by them for many years.
