I played it for awhile and dont think it is going anywhere for quite some time. An expansion is just great. Can no longer afford the monthly bill though so have resorted to conquer online (its free). The game is fun but in no way compares to WOW.. if you can afford it you'll likely enjoy it.
People seemed well satisfied with the updates they are adding. I guess we will have to wait and see. If I hear good things about it I might buy it but I heard World Of Warcraft is very time consuming and I don't have the time right now.
The Sims? Say what you like about The Sims, it has almost no competition so without the expansions there would be no new gameplay elements or options. The expansions are silly in numbers, for sure, but if they were pointless or bad people wouldn't buy them.
There isn't much competition to WoW in terms of what it offers, people will buy the expansion and I guess they will like it. I've never played WoW myself.
I really would hate to see the game end prematurely. I tried it on a guest account and really liked it. It was the first MMORG I've tried since that disasterous episode with Everquest. The only reason I am not a participating player is that I can't afford the monthly charge. Otherwise I would be on it in a second. Actually, it's probly better I can't. Form the little I've played I can tell it would be one that would steal my life and I'd really like to keep my scholarships. Alas, the life of a college gamer!
