Finding inteligent, mature life on the internet is like going to the Blue Oyster bar and being able to find someone not wearing biker-leather. (Police Academy reference for the win!)
I find that for the most part, your "mature" crowd tends to show up more in realism-driven games like my flight simulators (when played in realism-servers), or war-games driven by realism such as WWII Online. Granted, there's always the immature idiot no matter where you go.. but the "game of the week" is generally going to guarantee you the largest concentration of internet 'tards possible.
If you're looking for some fantasy-jones but don't want to deal with the online idiocy, I'd strongly recommend giving Oblivion a try. With just a small handful of community made modifications, it has become the bestest most coolest fantasy game I've ever played. SO GOOD! Beware the Xbox version though.. you'll be stuck with the vanilla version of the game and all its faults for all eternity (until someone figures out how to haxxor the thing anyway).

So they're keeping you on with the new team, with a corner-window office thrown in, sounds like? Sweet.
