I've put together what I think is a pretty solid SEGA lineup. I wanted to keep it down to my top 5. I've collected based on a criteria starting with fun, going through rules, layout, and ending on desirability.

There are a lot of other good ones, but these are what I feel are the pinnacle of what SEGA produced.
What would be your top 5?
If you think you're going to be cute and say something like "There aren't any good SEGA's", I'll bribe a mod to give you a lifetime thread eject.
