I think I have video game amnesia. Nowadays, I play something, watch the credits roll, and then involuntarily purge it from my memories. Admittedly, that's a bit odd, seeing as today's games are chock-full of lavish setpieces and retina-searing "water-cooler moments." Meanwhile, my childhood memories of the lo-fi Game Boy Dragon Quest games are still crystal clear. Legend of Grimrock reminded me why.
