Take a look at the Call of Duty series for example.
Call of Duty (2003), Call of Duty: United Offensive (2004), Call of Duty 2 (2006), were all based on WWII. Then they released Modern Warfare, which was a fresh and new change, added things like perks and experience. Then they decided to see if they could milk WWII for another release and made World at War in 2008. Then came MW2 in 2009, and Black Ops in 2010. Now they are working on MW3.
Maybe I'm not looking very hard in comparing these games, but they've done 4 games covering WWII, and 3 games covering modern times with almost identical gameplay (soon to be 4). And we as a public continued to buy these games. What about WWI, Vietnam, Korea, Civil War, or even the Revolutionary War. It amazes me how they have continued to be successful with 7 titles with so little differences. Am I missing something?
