18. The Madden NFL series. (Just about every platform, period)

Love it or hate it, there is no sports videogame that rivals it. Arguing against it is like arguing against using floor tiles in a kitchen: pointless. Hands down, it is the biggest money-making sports videogame in the world.

The biggest bump in the road came a few years ago, when EA announced it had secured exclusive rights to the NFL, NFLPA and NFLCA licensing. This, in effect, drove alternate NFL games like Sega/2K Games’ football game pretty much out of the running.

The big argument has been that without competitors, EA would slack on game innovation. That has not been the case, and in fact Madden NFL ’10 has seen a changing of the guard on the development team, including a re-emphasis on producing a serious, realistic simulation of football, rather than a pinball scoring-machine style of play where the game has typically fallen down, due to the inclusion of so-called “magic plays” that almost always work.

With plenty of innovation each year, the Madden franchise has proven that their biggest competition is… every other videogame out there vying for gamers’ hard-earned dollars in a down economy. People are buying fewer videogames now than they were at the start of the decade; but most are still keeping Madden at the top of their list every August.
