I can see the humor in it. But, for all I knew at the time (since you hadn't posted), it could have been a case of unoriginality from... uhm, someone with less knowledge of Ancient China, as in, having only played Dynasty Warriors.
If so, that's one whacked out obsession, that should be examined. Though, it would be funny to have Cao Cao conquer China nearly half a millenia before he's alive.
You've got to be kidding me. Someone was so unoriginal, they resorted to Cao Cao as their name? They could have atleast picked a lesser known TK person, but they picked Cao Cao.
Anyways, kiddies, this is why it's good to have a backup plan. Now, I switch from playing a slightly evil Ruler with ambition to spare, to an even more evil minister. The good stops here.
