The prices are actually pretty decent. The NES is reasonable, I'd buy the game I want for that much (about five games to equal fifteen dollars). I won't be subscribing to anything personally, but it seems alright. The N64 seems kind of pricey, I think a dynamic pricing between ten to fifteen dollars would be fair (fifteen for games like OoT, Mario 64, the classics), but I still own my N64, so there are only a few other games I'll need to get.
Speaking of which, I still need to get Kirby and Mischief Makers back from my friend.
