Trade server!
LOL jk, what a joke those are...
In all seriousness, we've already had a TF2 server. I did horrible. But as Psyche pointed out, the fact that it was balloon wars was the problem. A 24/7 instant respawn 2Fort server should do quite well in my opinion. Besides, what do we have to lose? I would totally play it.
By the way, its nice to see that these new AOs are launching a bunch of projects already. Keep up the good work!
