Yearly franchise titles - Good or bad?

[napoleon]

I wondered if there are any gamers out there who religiously purchase the latest edition of long-running franchises (and here I am mainly talking about sports games such as PES and FOOTBALL MANAGER etc) which has a new game every year?

Sometimes they merely contain minor gameplay tweaks and updated player listings which, perhaps, could easily be released as a data-disc or downloadable content instead.

Any views from ardent fans would be much appreciated!
