Re: Just wondering, does anyone play any "bought" games on Ubuntu?
I bought the Unreal Anthology too and was pretty annoyed that there was no native installer. In the end I had to do something of a hack to get UT2004 to work. There were instructions online.
I also bought Return To Castle Wolfenstein. The "Game Of The Year" edition, which also required some hackery compared to the normal edition.
I don't play either anymore - I believe Unreal Tournament 2004 works well in Wine with one registry key change, but I think RTCW is a write-off these days.
I try to treat the cause, not the symptom. I avoid the terminal in instructions, unless it's easier or necessary. My instructions will work within the Ubuntu system, instead of breaking or subverting it. Those are the three guarantees to the helpee.
