I enjoy most of the game franchises that were released by Japanese game companies and as well of a few select North American ones.
As I'm someone who likes every little detail, I search a lot even about small fractions of storyline-related plots or just plot-holes created on purpose - or not - by game designers.
Sometimes, I receive such info from fellow colleagues who share the same passion of mine - the one of being interested in details.
Just by searching and reading everywhere you can in the Internet, that's no secret. Everyone can do that. Depends on the amount of hours you're willing to put to use in order to retrieve information - If you succeed, those hours will be rewarded, If not, just put to waste. That's a risk everyone like me has calculated before.
