CT wasn't silly. It was lighthearted. There's a significant difference.
A major plotpoint involves reviving the main character with a doll you win at the fair.
Anyway modern WRPGs are trending towards grimdark grrr but I think that's sort of modern gaming as a whole and it's stupid as hell.
I wish I could pinpoint the exact moment it happened, really, but I can't. Sometime before Oblivion came out, though, as exemplified by the fact that Morrowind had a sense of humor and Oblivion did not*.

Basically what I'm saying is that Ultima 7's sexually frustrated unicorn, bee-loving nudist colony, and dragging a hapless 15 year old to a whorehouse totally would not fly today (although the last one... probably for different reasons. Sparky is totally funny though. He's like "8D" and Iolo's like ":(" and then the Avatar is all "Name job goodbye." Totally lulz. Totally, totally lulz).
* One game had you collecting the twelve whatevers to save a starving, injured fisherman. The other one had you finding pants for some guy that got his pants robbed.)
