@lastsonbackup: the thing that's backwards about that statement is that the majority of LPs out there, If they all play the same game, they don't actually offer anything new. You can press a different button at a different time or react to something differently than anyone else. the problem is that people can't watch the LPs for the game, the youtubers have to rely on people enjoying their personality to have any relevance.
They don't offer commentary, when I watch these LPs, they don't offer any insight on the level they're on or the game they're playing.
Honestly, you can do the Let's plays all you want, but if you expect to make a career out of it by not actually offering anything other than a play-though, then don't expect it to be a living.
