I do listen to requests, but if I can't play the game well enough to LP without it turning into a Let's Fail, don't have the game, or have the ability to record it, there isn't much I can do to fulfill those requests.
I kind of wish the like/dislike feature had a little space to fill out, anonymously, about what was good or bad about a video. Hard to improve to generic "I like it!" or "I dislike it!" options.
On that same note, I actually don't mind when people tell me what they think I'm doing wrong, and I do actually take it under consideration, but if you do have criticism and I respond to you asking for clarification or suggestions, I'd appreciate a response sometime in the following week. That type of thing makes it harder to improve.
Sorry, but the list of finished and upcoming LPs gets cut due to new space restraints. Yell at YouTube about it.
