Well as most people know by now, gamesas and Bethsada had a huge fight over the rights of whos going to make the Fallout MMO (For more details google Fallout lawsuit bethsada and gamesas).
But really when it comes down to it, I think the biggest topic is what do the players like. gamesas has given us Fallout 1, Fallout 2 and Fallout Tactics, While Bethsada has given us Fallout 3 (and others that arent part of the Fallout series).
While gamesas has given us some great games, Bethsada did show us that video games can be taken to new heights and be even more enjoyable than they previously were.
While Im not trying to barf alot of [I <3 Bethsada] advertising, a smart player
is going to ask themselves which one would you rather see made into a MMO, (your latest work in the Fallout Universe for each company).
A turn-based/real-time tactical role-playing game - Fallout Tactics - Brotherhood of Steel
OR
an action role-playing game - Fallout 3
To end I'll just say this... Good Luck to gamesas, Surprise the hell outta all of us, PLEASE we wants it.
