NOTE: I am not trying to bash this franchise or anything. I am just trying to satisfy my own curiosity.
Why do people keep buying Call of Duty games? They are decent games, but what makes all of you come back to this franchise, year after year? After all, it's not like there are that many changes made from one game to the next.
This is an experiment of sorts. Can anyone here give me a concise answer as to why this series sells as well as it does?
@benjaebe: Gamestop's return policy on used games allows you to return any used game within 7 days of purchase, provided that you still have the receipt. You get all of your money back, in cash(or whatever you used to pay for it). As a result, I now buy most single-player games used from Gamestop, then return them. Yes, I know it's bad for the industry. But, I don't make enough money to play all the games that I want to play, so this is an adequate solution for me.
Earth Defense Force 2017 wasn't the first game in the series, but I think it was the first one to be imported into the United States. It wasn't exactly popular, but it was a cult-hit. Probably one of the best co-op games on the market, as long as both players enjoy things such as B-movies, grindhouse films, etc.
