I'm kinda amused that people consider 3e more complex than 1e/2e.

Trouble is, none of the current editions is perfect.Fortunately, this is an imaginary dilemma.
People who want to play D&D have a wide spectrum of complexity to choose from, in several editions. I think it's a great situation.
Trouble is, none of the current editions is perfect.
Therefore, I propose we keep coming up with new stuff until we get everything perfectly right.

If such a thing is possible, I suspect it's only possible in retrospect: if we could write out the factors that constitute perfection, we could just use them to build it.I agree. Now only if we could only come up with a unanimous consensus of what is perfect...
Is there ultimately to be no D&D but RPGA D&D?
Once upon a time, D&D was by default a game that required no more work in character generation than rolling scores and picking a type and alignment; that had a simple, fast combat mechanism; and that encouraged expansion and elaboration to the degree desired.
