I guess my answer was based on the amount of years I've been playing. Hordes o' Andrew reminded me that Dark Sun was the first time I saw the 3rd starting level idea. Until then a 1-4 hp character was'nt unheard of. And skills were a few non-weapon profincies.
I thought that full hit points added to skills and feats was compatable to any "normal" encounter or situation I would put them in.
And starting at 1st level it gave them a second chance to see if they liked their character concept. Add in the fate point mechanic and a first level Conan character was more survivable and had more options than any first level AD&D or Gurps characters I've ever ran,
But as I said it could be my age talking, "You kids don't know hard. Why back in my day we had to make our D20's."
And this isnt a "what system is best" statement, please don't turn it into one.
