I find it way too easy to zone out while watching an LP from start to finish (unless it's for a game I absolutely cannot get my hands on). However, those things are a Godsend when stuck. So, so much better than going to Gamefaqs and leafing through mountains of words to find out why I'm currently stuck somewhere.
For the most part, all I've had to get are the games, which have either been on PS2 or DS, both of which I own, so it's not a big hassle. As for BBS, I have a friend with a PSP and a copy of the game who let me burrow it.
And I've got the 2DS anyway, so DDS won't be a problem.
