Some games have puzzles, and those puzzles can be fun. But just as often they are a pain in the ass.
They sort of remind me sometimes of parking. Here in Miami, every place you try to park your car, be it on the street, in a lot, or in a garage - they all have a machine with 20 buttons to press. It is never the same machine or the same buttons. Man I hate that.
So what would warrant you spending time trying to solve an in game puzzle?
