For those of you who have experience, how stable is blender 2.6 on Mac and Linux?
I don’t have much experience with Mac, but having tried out Linux, it seems fine. I was able to export a launcher for Linux 64-bit and the 32-bit executable, but I only was able to test the 64-bit version.
Thanks for the reply SolarLune! Just wondering, especially since I’m considering serious development on the BGE. 
Linux 32 bit is very stable for me. i’ve had far more crashes on windows systems than on linux.
(On Ubuntu, I haven’t tested on the other flavours)
