It's nice to see some good old fashion level design that teaches the player through the game rather than popping up an instruction screen. I think Journey is another great example. You're thrown into a world without any instructions at all, but you instinctively start moving towards the mountain because it's the only thing that looks different on the horizon.
Just replace the cowgirl doll with the box of SNES game. Every time i've gotten rid of an old video game, either by selling it or losing it, I've ended up going on ebay or local used game shops to find it again years later. In the end, I think it's better just to hang on to your old games, even if they just end up in a box in the garage or something like that.
