Wine is great, but I hate having both native and Wine version of Steam just to access Windows versions of games I have in my library. I wish Steam platform check could be overridden.

I guess that's just one more reason to choose alternatives like GoG, Desura and Itch.io.

Thanks! We work hard on it. If you like Wine and want to support its development financially, the best way is to buy a copy of CrossOver from my employer, even if you don't use it. Our salaries don't come from nowhere ;)

Yes, it has suffered major improvements, but it still doesn't run everything. Also, online games with frequent updates, break often.

Just my personal experience.

I'm using Kubuntu (just up-ed to 16.04 now), PlayOnLinux seems pretty good at getting things running but straight up WINE, for me, seems to take so much fussing with to get it to run stuff.

Also I read, that e.g. Wine+Tomb Raider blows the native Linux TombRaider out of the water, in regards of performance.
