I wonder who said anything about Shakespeare and faux-British accents, other than you?
Look, just to be perfectly clear:
- I've done semi-professional theater (i.e., I've actually been paid to act on stage). Granted, it was hardly a sum worth talking about, but nonetheless . . . .
- I've performed Shakespeare any number of times. Doing a convincing British accent is hard.
- (For example: I love the V for Vendetta film. And the one thing that still pulls me out every time is that Natalie Portman's British accent is still just a tiny bit . . . off. It's just touch too pure, too affected to be totally convincing).
- I'm not casting aspersions on anyone who actually tries to act in character during roleplaying, or uses any or all voice characterization techniques to help them feel more immersed. I've done it myself any number of times.
I've watched some Critical Role, and while I found it entertaining, I'm thinking of the one actor whose primary character interest always seems to be grog, and he voice acts that character as a big, dumb, lovable meathead.
Fun character. Easily pictured in context of the game world. But if the point is simply to "act out" by having your character speak English with a British / Scottish / Irish / German / Russian / Italian / Israeli / Jersey / Boston / Spanish accent, that may be fun, but if it's not backed up by an intent to have a character-driven arc, it's all just window dressing.
