Baseball Stars and Super Tecmo Bowl were my two favorite all time SNES games. Played them for hours with a couple of friends. We ran leagues, kept stats, kept record books, etc.
Eventually I started playing Baseball Mogul. Much more in depth game that I was fascinated with for a few years. Moved onto wolverinesports and their pro basketball leagues. Now I run a 30 team sim league. Lots of time spent but lots of fun also.
