The improv theatre and cooperative storytelling aspect of tabletop RPGs haven't come close to being approached by PC games as of yet.
Trying playing some tabletop D&D with a DM who's a professional screen-writer and some actors for fellow players and see if WoW can touch that.
Precisely.
WoW might look like a fine arcade game, but isn't worth squat in a competition for actual fun against "REAL" rpgs.
I game once a week usually sun these days. Session begins with about 1 hour of general chat as the host's kids are seen to bed. Most of us like munchies as much as the next person, and often the host has something homemade, plus one of the players has a penchant for over the top cooking that gets brought to the game. Ain't going to get any of that with WoW eh.
We have a large stash of minis, but usually we lack the actual correct figure. On WoW you might have the proper image, but heck, if the DM describes the creature and you can't imagine it, you have my pity I suppose (I have a great imagination myself).
We like to laugh and joke about the dreadful dice rolls as well as the how did you manage that successful dice rolls. We've knocked off hopelessly impossible monsters, and we have had our butts near stomped by totally loser creatures too. In WoW a 10th level monster is always only what it is, never any surprises. You never get to kill off a 70th level monster with ******** luck in WoW, but we have knocked off ultra monsters simply because we came up with a stunt the game designer could never have foreseen.
Player creation. Don't even pretend your WoW characters are anything but uber maxed out killing machines. Oh whip dee doo, like that is so special.
Right now I am playing a Barbarian half ogre that only wants to hang out with halflings, because my PC wants to discover the ultimate spice and become a master chef. Still, he's good in a fight. Hard to hate something that can just grab the impossible AC adversary and hold onto it while ANOTHER PC has fun whacking it while you hold it for them
Grapple, not to be taken likely. Plus, if you can't get past the super dwarve's mega AC, you can always just settle for smashing it into the ground, or a tree truck, or other enemies, or if you are lucky, just heave it out into a lake
Table top RPGs will never be as "easy" to sell as PC games, but PC RPGs will never be even close to as fun.
