Game idea

So why has no one made an MMOFPS yet? It might actually get someone like me to try out the whole MMO thing. You could start out as some sort of class of character, be it a straight soldier, a medic an engineer, a scout whatever. Start with a basic weapon and join groups who have to perform missions like raids on emplaced structures or blowing up a bridge or whatever. Over time you could earn experience which would improve your abilities sort of like they do in Wolfenstein Enemy Territory. As you go you could find more and better weapons. It could be a nice change of pace from the stale WoW and CoD clones every other company is cranking out these days.

The only real problem I can think of with this is is that it'd be a real bitch on the servers. An MMO just has to deal with crunching numbers to calculate what happens. Did that guy just hit me? Well, let's do a check on my evade percentage score or whatever? Did I get a critical hit, well, 8% of the time I do so random number generator: nope, no critical hit. With an FPS though to see if that guy missed me the question is dependant on my position in 3D space at the time of his shot and as for whether I got a critical hit, well, did you hit the chest or head hitbox with your shot? There's a good bit more processing there. I'm sure it could be figured out at some point though, so maybe we'll start seeing these in the future. After all, the original MMOs had to wait till a server farm was capable of hosting thousands of players while still being reasonably profitable for the company running all of those servers.

Any thoughts on that one there, interwebs?
