Dagger75,
NEVER play the same game every week for a long time. You will burn out, no questions asked. I am surprised some other players do not feel the same way by now. Perhaps you have attended more games than everyone else, with others missing a session every now and again?
My advice to ANY gaming group is play different games. Play Magic the Gathering as a group game (it's a very different experience to make a group deck than a competitive deck), play a complex board game, play frisbee, get boff'em weapons and beat the **** out of each other, or (shock! horrors!) play another RPG. Even one with a different genre but d20 rules is a good change of pace.
Do not be concerned if you have burnout on one game. Playing one game and dealing with only one genre tends to make your mind tired and your ideas stale. I know this from personal experience. I used to only immerse myself in genre stuff, and found I was beginning to come up with the same hackneyed plots over and over. I started reading spy thrillers, watching "chick flick" dramas and Lifetime channel (don't laugh), and delved a little into horror, nonfiction, and even psychology textbooks and non-european history. It was one of the best things I ever did. How else would I take a hack-and-slash module, take the plot from a Lifetime Movie of the Week, and insert it as a subplot into the module I was running?
Get out while you still can, because when a game stops being fun, then why the heck are you playing it?
