[ubuntu-za] Games?

[Hardie Botha]

Hi all

I am looking for some good/reasonable games that's either free or 
reasonably priced for Linux.  One I can recommend is America's Army 
which can be downloaded for free at

<http://www.happypenguin.org/show?America%27s%20Army%3A%20Special%20Forces>
Unfortunately the  porting for this game to Linux is no longer 
officially supported, so the Linux client is behind the Windows client 
in version numbers and servers are getting scarce.
This is a first person shooter, there are also a couple of good strategy 
games out there I believe

Can anyone make any suggestions?  I am looking for first person 
shooters, strategy games and to a lesser extent role playing games.  It 
would be a bonus if it could interoperate with Windows clients and 
servers (Similar to AA).

What are you playing or doing for entertainment on ubuntu/kubuntu?
