Actually, I really don't suggest 4e. Don't bother.
What I WOULD suggest is getting into Pathfinder, which is Paizo's compromise between 4e and 3.5e. They took all the kinks in 3.5e and smoothed them out, without going way overboard on the simplification of the rules, like in 4e. Here, check out the SRD
, you'll see what I mean. They changed a lot of stuff,and for the better.
Ex: Pathfinder simplified all of the weird useful rules like Trip, Grapple, and Bull Rush that everyone wanted to use but nobody could because the rules were so complex. Now, all you have is a Combat Maneuver Bonus and Combat Maneuver Defense, and it works just like an attack vs. Armor Class, except it's using your CMB against your opponent's CMD.
There's tons of stuff like that. Plus, the setting for Pathfinder is really neat in places, and is suited to a wide range of playstyles and genres. Paizo really went out of its way to ensure that Pathfinder was flexible (there's even a continent dedicated to steampunky stuff, entitled the "Savage Land of SuperScience," although if you wanted that you might as well just play Eberron with Pathfinder rules, the way my Mom does).
P.S. Sorry for derailing your thread, Ross. I guess you kinda started it, but still. This is a bit overboard.
