Yeah, my favourite settings are Dark Sun and Dragonlance.

First I'd add the basic D&D races - gnome, halfling, dwarf, elf and half-orc. Then yeah, it would be cool to be able to play thri-kreen and half-giant. I'd give a very low dexterity and low wisdom to the half giant though, to compensate for his extraordinary strength. There may be a problem also, if the game allows a half-giant and a halfling to wear the same armour.
Then there are the 'evil' races. Orc, goblin, kobold, kuo-toa, lizardman, troglodyte, salamander, formian and drow would all be nice to have as playable races, provided some kind of balance can be achieved. The rest are too powerful to use as player race.
Other fun things... The disarm and sunder actions. Disarm can't be done without teaching the AI to go and pick up a lost weapon. Sunder means items can be totally destroyed, meaning you may lose your +5 sword of doom or heavenly shield of elemental immunity.
Multiclassing. Simply because it's complicated and prone to bugs. Also it's unusual in fantasy works - you'll see rogues, barbarians and wizards in films and books but rarely a half-wizard, half-warrior.
Proper summoning, can't be done unless your bestiary contains the entire Monster Manual. Proper polymorphing, can't be done for the same reason and because of the mess in terms of size changes.
Non linear campaigns, non combat spells like talk to animal or talk to the dead, hydras where you can target a particular head, flying, horse-riding, swimming, etc, etc, there's a whole lot that can't be done (or is very difficult to do) in a cRPG.
