Why does no one bother to make a FPS MMO?

It would be awesome! All I see that would make it successful would be:

Cartoon graphics (TF2, little lag)

Huge open world area

2 Factions against each other, heavy PvP.

CoD 4 style, with a mass amount of weapons/upgrades/armours etc

Leveling system

2 on 2, 1 on 1, or even 32 on 32 arenas, or just open world PvP to obtain the greatest rewards.

Actually, you pretty much described Savage 2, without the cartoony graphics. Give it a try, it's on sale right now on Steam for 9.99

In addition to WW2 Online, there's also Planetside.

Also, there's Huxley to look forward to.

tf2 graphics, huge world, pvp 32 vs 32, leveling system? it'll lag on A LOT of machines. and how would something like that work out? jeez.

just check out battlefield: heroes, it's not a FPS, more like a TPS but still qualifies for a whole lot.that or hellgate: london.

EDIT: you are basically looking for fallout 3 ala MMORPG.
