considering WoW's first expansion is just about finished you will never see any posts about done it all. That game has infinite life possibilities because right now its more complete content wise than most current MMO's say for EQ1 and all its expansions. Horizons isn't even in the same league of Eliteness that Wow is and never ever will be unless a company like SOE, MS or even Blizzard buys the game. They will never have that kind of investment. The MMO market is simply to competitive more so than the Auto market.
Tulga games can carve out a niche if they know thats what they have to do. I am not seeing that right now.
