I think if not for Pathfinder lots of the old 3rd ed crowd may have eventually given in to 4e, or at least a sizeable portion of them would have.
NOTE: This is not an attack on you Mournblade. Just want to make that clear at the outset.
And this was another one of my pet peeves from the 4E supporters at the beginning: "Stop your griping, you'll be playing 4E eventually anyway!"
As if it were the ONLY game of value in town. If there were no Pathfinder, I'd be playing 3.5 with Trailblazer mods. Or I'd have moved to FantasyCraft. Or FantasyHERO or maybe gone full time back into Supers Gaming. But I would NOT have gone to 4E any more than I would have gone to Palladium Fantasy, WHFRP or any other RPG that I've tried and didn't care for.
Bottom line, I would probably be playing something. But it wouldn't have been 4E.
