Errrrrrrrrrrrrrrr,

I loved 7 & 8, and 10 is in my top 4 as well, but WOW, 2, 4, & 6 are really good and I love the stories overall there. Plus 9, 12, & 13 aren't my faves, and the very idea of the online games being in the main numbered series really bugs me. So do sequels, most of which exist in the latter series.

I'll go with 1-6. Seriously, if I had to say which were made with better overall quality, there's too much overthinking going on in later games, and the early ones felt more adventurous and genuine.
