I want to add some information to the discussion:
I had the same problem recently with Chromium-BSU on PCLinuxOS LXDE and solved it by moving libGL.so.1 libGL.so.1.2 out of /usr/lib as suggested by Texstar. But, with PCLinuxOS Education (Openbox) the two files are still in /usr/lib and the game works perfectly....
So maybe it will help you solve the problem at another level.
