To me, it's a lot of distinctly 1st ed AD&D elements: alignment languages, silly dungeons that would have cost my character several million gp to duplicate the stupid magical effects that were encountered which made me wonder why they existed in the first place, the UA barbarian aka the grossity, polearms polearms polearms, exceptional STR (although that unfortunately carried over to 2nd ed and was my second biggest gripe of the system), "humorous" methods of humiliating PCs, and other things that I can't think of right now. To me, "Gygaxian" is a pejorative. But I do honor the man for creating, or at least popularizing, the RPG category of gaming and didn't like the treatment that he received from TSR at all.
