From what I can gather, it just seems like you're pissed games you don't like to play come out with sequels all the time.

Just for example, it IS necessary for at the very least, one new guitar hero game a year. You get 60ish songs, and they can just continue to get new songs and pump them out non-stop. I honestly don't care if the backgrounds, guitars, and characters are all the same, I just want more songs.
