Sonic 4 was on the list as an example of a recent game in 2D that plays in a way that I enjoy (platforming, never mind the flaws... I personally prefer a lot of games like Sonic 4 and not a lot of puzzle indie games... and anyway, it was nice to have Sonic back in its full experience after so many years, so the mistakes of the game and the obvious fact that it was inferior to the Genesis games, were overshadowed by the joy of playing a new Sonic in 2D).
But be cool, this game isn't even on my Top 100 list. Although, Sonic 4 Episode 2 had a great soundtrack.
These are the games I mentioned that DID make it to my personal Top 100:
Final Fantasy VI
Chrono Trigger
Valkyrie Profile 2
Super Metroid
Star Ocean: The Last Hope
Eternal Sonata
RosenkreuzStillette
Portrait of Ruin
Order of Eclessia
Another day, I can post the complete ranking so anyone with a ranking can post it, and comment on mine's.
