120 players at all times, having to mash the connect button untill you get a spot in there.
Do you remember that special event chadz and cmp organized to test new servers? Arena, 250 player cap methinks, full to the brim. Maybe even more. I do remember that my PC was dying, chugging couple frames per second. But it was fun while it lasted
Native siege often have more than 200 players but that testing was special.
