Why isn't 5th mix up there? That's my favorite mix, second being 4th, 3rd being Max. It was the most danceable for the mixes, and had a lot of really good songs there we never saw again. Plus, it was the first game to start working at 60 fps, and the last to use that nasal announcer, so it'll always be special to me. Plus it's the last game that taught me how to play "Sana Molette Ne Ente" without mods, until Max 2 came around...
I'll be yet another "where is my 4th Plus?" voice. In fact, where is my 4th Plus SOLO in that list? I got my start on that cabinet and it's still my favorite to this day for all the awesome within.
5th Mix. There are plenty of good songs on there (including LONG VERSIONS!), and the stepchart to INSERTiON is just plain awesome. "No Limit" and "Tribal Dance" are a lot of fun, too.
