I'm sure there are going to be a few of these going on. But I'm planning on running one as well; just playing the game and giving my thoughts on it as I go.
I tested it earlier with SWTOR and it worked fine, but obviously I've never tried streaming Tera before (dur) so hopefully it'll work correctly. If anyone wants to see some gameplay they could actually read but couldn't get into the beta for this weekend, feel free to check it out. Should be starting up as close to 2PM CST as I can
