Shadow the Hedgehog - Introducing guns was definitely an awkward step sideways, but it was a fun game nonetheless and I enjoyed it.
Sonic Heroes - Everyone likes to bash on Sonic Heroes, but I had fun playing this game.
Sonic the Hedgehog (2006) - It'll always elude me why people hate this game with such fury that burns bright as a thousand suns. Other than framerate drops, I thought this game was awesome. It was like Sonic Adventure, which I also loved. Honestly I wish they'd make more "open-world" Sonic games. Sonic Adventure, Sonic Adventure 2 and Sonic(2006) are easily my top three of all the Sonic games.
White Knight Chronicles - Okay, I don't know about hate, but I definitely see no love for this game. I absolutely loved White Knight Chronicles. I've heard some complaints that it was absolutely slow, but that's about it. Which is nulled basically because of the way White Knight Chronicles remasters the original with graphical and mechanical updates. Going from WKC to WKCII feels more like going from Disc1 to Disc2, rather than from prequel to sequel and I think it was done brilliantly. Also, I'm going to spare you my argument why Avatar is a brilliantly executed character and why I wish to see more characters like him/her.
Devil May Cry 4 - Dear lord the hate I've seen for this game. I don't honestly think it deserves the ire that people have raised for this game. Now, if someone was to say it was the weakest in the series, then sure I'd agree. But it's definitely not as bad as people shout out.
