I sympathize with Bullgrit but I'm of the opposite persuasion. I avoid posting in the 3e/Pathfinder forums because really I have nothing positive to say about what I now consider the absolute worst incarnation of D&D ever. I just don't like to dog on someone else's choice of systems. I only bring it up now because its relevant to this discussion.
When 3e first came out, I thought it was brilliant. Like trading in my broken down 2e beater for a sleek sexy and sporty new car. But after playing it for 8 years, I slowly became disillusioned. Mechanical systems that I thought were great at first, like monsters following the same rules as PCs, began to lose their luster in actual play.
Over the 8 years of 3e's life, my love became like, then slowly became frustration and exasperation. House rules bandaged over some of the flaws, and by the time 4e came out I pretty much viewed 3e with utter disgust. Like a vampire, it literally sucked the joy of the game out of me. I used to live, eat and breathe D&D when I played 1st and 2nd edition. But with 3e, D&D stopped being fun and started being work. And games are supposed to be fun. For some its a funny internet meme, but 3e really did kill my inner child. And I still haven't fully recovered.
I agree with Bullgrit that 4e is a different game than all the prior editions of D&D. It is different. And thank heaven that it is. In my opinion, its a far better game because of it.
But I feel for those of you who feel that 4e is no longer the game they recognize as D&D. I feel for you, because thats how I felt until 4e came out.
But unlike before, we now have a plethora of published options to suit all D&D tastes (queue Three Amigos jokes!

). 4e, True20, Fantasycraft, Pathfinder, or OSRIC, and more. I think its fantastic they we can all now freely play the supported ruleset that appeals to us instead of being forced to play one or the other because its the only game in town.
