Now I think on it, gaming's taught me a fair bit. I mean, I wouldn't know as much on folklore and mythology - always my favourite subject - as I do now if it wasn't for the Final Fantasy and Shin Megami Tensei series, and Ôkami. Due to gaming, I've learnt about imaginary number (a term referring to the hypothetical square root of -1, expressed as i) and zetta (10 to the power of 21, or a sextillion).
I could also fit dozens of The World Ends With You quotes here - "only by allowing strangers in can we find new ways to be ourselves", "don't let life hold you back", "give up on yourself and you give up on the world", "keep moving forward, because someday your dream will find you", "enjoy each moment with all ya got" (I know, that's five, but I said I could fit dozens, not I would).
But the most important, most crucial thing I have learnt is this: if you see a guy with silver hair, and he's not really old, run like f***.
