Rojosama: I bought this wit the understanding it WAS ALREADY multiplayer thanks to all the gameplay videos and the description of the game. How silly of me to assume whatever is written is actually whats in the game eh?
And all they ever say is when confronted "we're working with GOG to enable this" And then nothing. I had several friends who were ready to buy it, and non of them bought it because of this nonsense, I bought it because I was foolish enough to think they'd quickly fix it, now I'm feeling that HBS simply decided to not support their GOG version, because there's plenty of activity from them on the Steam community page.
My advice, make a stink, tell them publicly how full of BS they are on Facebook and Steam.
