RBI Baseball was great, but I preferred Bases Loaded II when it came out.
Also, the original Road Rash for Sega Genesis was great. It finally put together the fun of games like Rad Racer, but you could make it past the third level and enjoy a single game for 30+ min.
Other great games not as popular at Tecmo Super Bowl but were still very good included Ninja Gaiden, RC Pro-AM, and Bubble Bobble. If you have 20 minutes to kill, Blue Marlin is also fun.
