Feel free to add me on Steam guys (username below).
We had an RC2 group of 150 or so players for RC2 online play, although this was mostly from me scrabbling around trying to get players together after initial interest had wained (mostly due to never being able to find online players!).
I'll be looking to get an RC3 online group set up as soon as we have a release date, and plan to call on (read: spam) all of my RC1 and RC2 contacts to join up if they're thinking of getting the game. That's about 200+ players at last count. If we can get anything like 50 players at launch, who can see if anyone's online and arrange games/tournaments etc then we'll be in far better shape for online play, and have more of a chance of building it this time.
Geez TruBlu/HES don't make this easy do they?
