Is this thread just an excuse to talk about Fantasy High? Fuck it, I'll bite
Fantasy High is the only even acceptable live play I've ever watched, and even then I did feel immense agony watching it. On the downside, the DM clearly didn't know the rules very well and the constant use of insight checks and allowing repeat checks made me want to fold into progressively smaller pieces. Then there are just the universal problems of live plays, like having to sit through the umming and erring the players do in combat. Then there're things I look at and can't help but feel judgemental about doing, such as the occasional bit of railroading (it's necessary, but railroading is done best when you don't see it). Now, on the positive side, I quite appreciate the interesting terrain they used and the effort of actually editing the stream in places (SFX, for instance). It was quite amusing and I found the setting quaint, and the characters were somewhat fun.
Ultimately, it isn't something I would say I regret watching, but I also won't pretend I would've stuck with it if it were any longer than it is or wasn't complete by the time I watched it. I also stuck with it largely because I saw they had a modern game and thought they were using Vt[M/R], but decided to sit through this one first.
