First Vin Diesel and now this. Recently retired MLB pitcher Curt Schilling is heading up a game studio that has been working for the past 24 months on an MMO. The working name is Copernicus and it is tentatively dated for 2010.
Author R.A. Salvatore (Forgotten Realms books, notably the Drizzt series and Icewind Dale series) and artist Todd McFarlane ("Spider-Man" comics, creator of Spawn) are the other founders of the studio, along with Schilling.
Digging through some old articles it looks like he has some decent people working on the project and running sections of the studio.
*company CEO is Brett Close, formerly of Midway and EA
*UI designer is Irena Pereira (WoW, WoW:BC, WoW:WotLK)
*music by Aubrey Hodges (King's + Space Quest, Doom, Quake)
*art design by Thom Ang (Medal of Honor, also from X Files)
*system designs by Travis McGeathly (former lead designer of Everquest)
It is being developed on the Unreal 3 engine.
Looking into it at first I figured it would be some whimsy of his as I knew he was an EQ addict from interviews of him on the Red Sox. It really seems this project is moving though and he has a lot of talent on the roster putting it together. I will probably end up keeping an eye out for more news now.
