They are "porting" browser games? WTF? A browser game? Needs to be ported?
Hey, EA, why not have Dragon Age origins or something like that as a native version?
Ubuntu Software Center? Is that distribution independent or does stuff there only work on Ubuntu? Because clinging to one distribution would mean to have nearly the same problem like games for Windows. It wouldn't make things better.
A "Linux version" of something should mean a package of software that runs natively on any Linux kernel based OS. Give a recommendation of the least kernel version number (2.6.x) and maybe a few major libs that can be expected on about any (desktop) Linux distribution and if you use exotic things just make a static binary. Maybe demand the user to have a working OpenGL implementation. But that should be about all. Then you could really speak of a "Linux" version. And probably something like this might also run straight away on a FreeBSD.
Stop TCPA, stupid software patents and corrupt politicians!
