Let me get this in before the eventual lock...
I find it highly amusing that many of the complaints launched against 3e and 4e are blatantly in 1e or 2e, but often "ignored" by the rose-tinted glass of nostalgia.
To Wit:
Game-slowing subsystems: Sure, grapple was a pain and nobody ever remembered the steps to it, but did you ever try to punch/wrestle without the book open? Or Turn Undead?
Power Escalation via Supplements: Ever heard of Unearthed Arcana? Complete Book of Elves?
Meta-gaming: The Tomb of Horrors was a metagame-laden module. The puzzles didn't care if you were 1st level or a demi-god, just how smart the player was.
Role-Playing Vs. Combat Rules: Open Up your PHB for any edition. How many pages are devoted to combat resolution (including combat-use magic)? How many are there for skill use, social encounters, or "role-playing" concerns?
Similarity: "Hi! I'm a fighter. I'm specialized in bastard sword." "Hi, I'm also a fighter, I'm specialized in battle axe".
Magical Item Dependency: Because the classes typically only had a few options for customization (choice of weapon spec, % of thief skills, rangers favored foe) most characters depended on magical items to make the different from one another mechanically. A high-level fighter stripped of everything wasn't much better than a low-level fighter, just better at hitting and taking damage. Compare with a high-level mage vs. a low level mage without gear. No contest.
Magical Item Acquisition and Leveling Speed: I recall someone long ago disproved the myth of 1e or 2e's "low magic item" and "slow leveling" myth. Both were only possible with DM intervention (giving out less treasure, no XP for GP), which puts it into the realm of houserule, and similar houserules can and do exist for 3e on as well.
Metagamism, Redux: Wait, if I'm an elf, I can be a mage, thief, or fighter, but I can't be a druid, bard or paladin. I can be a fighter/mage (earning XP at the same time in two classes) and ignore the penalty to casting in armor, but if I was a human and dual-classed (fighter into mage) I couldn't cast in armor, and never level up in fighter again? How is that balanced? Oh, right, I'll magically stop earning XP after a certain point, negating the sole-purpose for adventuring.
So in the end, I guess I don't see many of those criticisms launched against the post-TSR editions can't be retroactively applied to earlier ones as well.
