My top favorite games are: 1) Techmo Super Bowl (NES) 2) NHL Hockey '94 (Genesis) 3) Madden 2004 (PS2)
I have to agree that Madden 2004 was one of my favorite PS2 sports games. At the moment though, I'm really enjoying UFC Undisputed 2010. It delivers the action and intensity that I'm looking for in a game.
There are a lot of great games out there. However, I prefer the simple games with less special effects and graphics. In no particular order: 1. super mario brothers - super nes 2. pocky and rocky - super nes 3. final fantasy series
