It's the familiar way in which the game sucked when you first got really into it. So, it's wizards being killed by housecats at 1st, and wishing for ultimate power at 18th, and spells that say 'save neg' doing nothing at high level, and theives being worthless and clerics being heal bots, and fighters become fuedal lords at 9th level, and your character being defined primarily by the items he's found and curses and wierd abilities he's accumulated. Or, it's wizards having unbeatable save DCs, rogues wimpering when confronted with undead (or constructs or oozes or partial concealment or long legs) and druid animal companions beating up the fighter, and CoDzilla rampaging through the campaign. Or whatever.
It's whatever was wrong with the game when your formed your impression of it that might latter get 'improved' away.
