I think yearly releases are way too much. I think even 2 years between entries is pushing it but overall is acceptable. I think there should be no more than 3 games released in 6 years or in any given generation of hardware. Id rather the developer publish more DLC and keep the story going rather than release a new game every year and then release DLC on top of it. But then again, why do they care what I think? The simple fact is people keep buying the yearly rehashes of Guitar Hero, CoD, madden, and the like and thats why it continues. If you people really hate yearly updates then dont buy the game. Thats the only way this stops.
Long Live SHIO!
