rompus: Switched from (unknown to me) pirated windows to Ubuntu - can't seem to handle my games. I am e-idiot - is there an easy fix?
No, there is no easy fix. Windows software does not run natively on Linux, however you do have options. You could run Windows within Linux via a virtual machine, but that does require a legitimate copy of Windows. Without a legit copy of Windows, your best bet will be the previously mentioned Wine and its variants, but that is a bit hit or miss. If you run into issues, you might have better luck visiting the Ubuntu forums and asking questions there about running specific games.
i666an: There are commercial versions of wine also - google playonlinux (yes all 1 word) that is constantly updated as well.
Clarification: PlayOnLinux is not a commercial version of Wine, it is a free front end GUI for Wine that makes doing things with Wine, especially running games, quite a bit easier. The commercial version of Wine is
CodeWeavers CrossOver.
