Why not? Hell, just get Matt to do it since he hasn't appeared in any of the RPG videos. It doesnt take long to skim over 5 hours of an rpg in an FAQ and go "ok use the lightning character in the next dungeon and look for a chest with a cool sword in it" or " the FAQ says X is the first town that sells Sprint Shoes and its a mandatory accessory"
They record separately way ahead of time in huge chunks, so none of them are necessarily open to do stuff.
Though really, if you wanted that then they should just have a walkthrough on hand. Or they'd just do that before recording. Part of the point of a double blind LP is the reactions and blind part though.
My favorite LPs tend to be ones where one person is basically an expert/can guide the person playing. Ironically, what you're asking for in terms of "playing well" is best exemplified in doing RPGs as Chrono Trigger, since Pat plays the game well and is super completionist.
Also, yeah, I'm with croten, personally.
