bossonova: What do you guys think???
*facepalm*
This is as flamebaitish here as it was on the Steam forums to be honest. You don't give us any insight into what your motivations are whatsoever, how are we supposed to know where you should buy it? People who prefer GOG will say GOG, people who prefer Steam will say Steam.
You could at least ask what the differences between the two are or whether the Steam version has DRM or ... well, you know, something relevant and factual rather than something completely subjective.
