Opinion: would you go for a game with pre-made PCs?
It depends entirely on the game and the characters. I've done pre-gen characters a few times, including my first-ever game on RPOL, and the secret to it working for me was having a character available that I resonated with in some way. It didn't even have to be a character type I'd normally play...it just had to look like something that would be FUN to play.
I got into gaming long before I got into theater, but in both cases, having a character that I could enjoy in some way makes all the difference in how fun the experience is.
If it was a system with which I'm not familiar, a pre-gen could be nice just to help get the game rolling faster (granted, I'd want some latitude for making it MY character, as opposed to A character I'm just playing...and some explanation of just how good or not good the character is, based on the stats). If it's a game I enjoy and it's going to be a quick one-off adventure, pre-gens are nice because I don't feel like I'm investing a ton of time into building a character that's only going to be used for a few months, at best...I'd still want to be able to tweak it a little bit, though. That was one of the things I loved about the old WEG Star Wars D6 rules...they had templates, plus rules for tweaking the template to be more what you wanted, and I could take someone who had never played RPGs before in their life and have them up and running in a Star Wars game in an hour or so, which is a far cry from any of the other systems I've tried in the last five to ten years.
