I saw an advert on steam "Last chance to Pre-Purchase"
Hmm i don't know, maybe i'll just purchase it instead, you know when its released and some reviews have come out.
I've been burned enough times buying crap before reading the reviews. People really should take better care of their money. What does the paying customer gain? The company gains your money and the interest derived from it for the days/weeks/months before you actually recieve the game. The customer gets the game several whole hours early before the shops open for those still buying physical copies. Maybe they get to pay for being a beta tester too.
I really am mystified as to what customers gain of substance!!
