Never really understood people who make money from recorded gameplays, but on the other hand I do like watching Let's Plays, so...
Hmmm... Never considered watching an LP to be a replacement for actually playing the game; in fact, I've discovered quite a few games this way that I later bought or consider buying. Including the one game that, in a way, saved my life, and that LP was found by sheer coincidence. I might use an LP as a guide, or to determine whether I'll be able to play a particular game at all (because I'm ridiculously bad at anything action-based), but never as a replacement.
Though, to be honest, most LPs I watch are of games that I've already finished, because it's interesting to see how other people come up with solutions to various problems; also - a chance to discover something I might've missed during my own playthrough.
I'll drop this hard question into your lap.
I thought Youtube video producers couldn't make money off Let's Plays. Because that's what Youtube's rules say when you try to become a partner - you can't make money if you don't own the full copyright to whatever you're doing. Hell, it's the reason why I never let them monetize some of my videos which have dozens of thousands of views.
And now people are complaining about it?
It isn't complaint, its clearly a debate I'm seeing here. Sure, I might be here to BBQ Nintendo the moment they make things worse, but that's me. I'm also wanting the views of others.
