psht, I've learned all my from video games and I've turned out just fine. There are just certain things you can't learn in school man.

If people are red, it's because they're either invulnerable or close to dying, depending on their facial expression. Turtles are evil and must be stepped upon, watch out for the ones with wings. If someone is so dizzy they have trouble standing on both feet, it means you can kill them in a brutal way. If you are jumping across a pit, you can bet your blue ass a green poison-barfing lizard will jump up and pull you in. Don't worry about spending money on hookers, just kill them afterwards and get it back. If you HAVE to walk under a chandelier, at least try to trick it into falling first. Sometimes it works to shoot locks open with guns, but it won't work if the lock is rusty, in which case the only thing that will work is oil, etc etc.
