3.X and I have a long, sordid on-again-off-again affair.
Things would go great between us. We'd go out and do battle with the forces of darkness and stay up all night just laughing and killing orcs and generally getting to know each other. Oh sure, there was the occassional squabble, the occassional level 1 wizard eviscerated by a housecat -- but for the most part, we got on well.
And then 3.X would change. We wouldn't spend our days (and nights) slaughtering the bad guys, we'd spend them instead huddled in a circle, casting spell after spell after spell, and then waltz in only to find our foes dead of old age and boredom. Inevitably, we would go our separate ways.
But the lure of adventure is a hard addiction to master, and weeks or months later, I'd find myself back at the table and, like a burned-out junkie, rolling up yet another 1st level rogue to sate my need. We both knew it wouldn't end well, that in a few months time the game would change and we'd remember why we left in the first place, but until then... oh, until then it would be great except for the guilty knowledge that the relationship wasn't really GOING anywhere, if you know what I mean.
When it comes right down to it, I suspect E6 would have been more my cup of tea, insofar as 3e was concerned (mechanically, not thematically), but I never found a group willing to try it. They all liked the IDEA of higher level play, but the reality never quite lived up to the hype.
