In addition to the list of 84 free games covered on LinuxLinks.com, they also have a list of 42 commercial titles available on Linux.  In order for a game to qualify for this list it had to meet the following requirements:

• Released under a proprietary license with a fee required either to purchase the game, or a monthly charge
• Not require Wine to run. Wine is a compatibility layer for running Windows software

So if you really couldn't find a game to suit you from the 84 titles previously mentioned and you are willing to pay, have a look at this list.
