So, what do YOU guys think/know is simply impossible in Sonic Robo Blast 2?
Fun.
I kid, SRB2 is tons-o-fun.
Voice chat is impossible. I mean, it's Doom. Although more tedious, I'd rather use Skype and then open SRB2.
I can't think of any technical reason voice chat wouldn't be possible in SRB2. I don't know of them personally, but I'm sure there are libraries out there that make adding this sort of thing to your game super easy. In fact, there's probably ways to get it to connect to an existing Teamspeak or Mumble server that splits games off into their own rooms without needing to install a client.
