This evening (June 4th) Epic held a MOD chat with IRC chat with Steve Polge and Cliff Bleszinski off of the UT 2004 team.
The chat was a bit messy and off topic untill the mods at the IGN network got the whole "how do we do this" cleared up.
Makes me wonder why these events are never better organised. :P Head over to www.ataricommunity.com for a chat transcript.
