Sonic R: I love it. I don't know why. The controls are slippery and thats my only complaint. I loved this game.
Sonic Adventure 1: I loved this game, too. It is the model for a great 3D Sonic Game. See, I've never had major, if any camera problems. I have never glitched something up and been unable to finish the level. Truth be told, in my opinion, people who had those complaints were doing something wrong. The music, the atmosphere.. It was amazing. Sonic levels were great, Tails was great, though I kinda wish we didn't have to bother racing all the time, Knuckles treasure hunting was enjoyable. Amy's gameplay, while slow, still had its moment and I also enjoyed Gamma's levels. Big.. Eh.. He's not the worst thing to ever happen to Sonic like alot of people act like. As I said, the music and the atmosphere blended together perfectly and the story was, while not the most compelling, perfect for getting Sonic out there in 3D.
Sonic Adventure 2: My memory card may say I played this more than SA1, but what it doesn't show is that I've been through SA1's storyline so many more times than I've bothered with "Dark" or "Hero" side stories. Knuckles, Rouge.. Ugh, why? Treasuring hunting sucked in this game. Eggman's gameplay? It was perfect, Sonic & Shadow were the highlights of this game, but I swear to god every level had a bottomless pit. Another gripe I have with this game is the music wasn't as fitting as it was in SA1 and the end story sucked. At least Chaos' betrayal MADE sense. This time? Biolizard? Where the heck did that come from? Whatever. The ending was also nice and emotional, but come on.. We all knew he'd be back. However, despite all the negativity, in the end I do enjoy this game, though I don't think it was the "best 3D game ever" (Thats SA1). I do think it was the last GREAT 3D Game.
Sonic Heroes: Oh.. God.. Where do I begin? Alright, well, it was.. Weird. Though, for what it was, I did enjoy it. However, it wasn't a Sonic Game. I did like the return of the Chaotix Crew, however it also gave us Team Rose and Omega, who wasn't needed at all. I brought back the Zone/Act format, though everything had a different name and wasn't named "Act 1/2". The levels were fun, though the bosses weren't memorable. Not alot of memorable music either. The story.. I'm not sure what to say. Barring Team Rose, it was okay until you realised it was just Metal Sonic becoming some sentient person and continuing the upstaging of Eggman which is getting really really stupid at this point. It also brought back Shadow and made us doubt what he is which set us up for his own game which is a sin. It did bring back Special Stages, but it still sucked.
Shadow: Never.. NEVER.. Has a Sonic game pissed me off so much. I am absolutely astonished at just how bad and mishandled this game is. The story sucked, the gameplay sucked, the characters sucked, everything sucked. It sucked, sucked, sucked. I wanted to eat my gamecube this game sucked so bad. The only level I enjoy is Sky Troops, and thats because the music is good and you can play it like a normal sonic game and forget all the other bs. The story? Oh my god. What were they thinking? I wanted to strangle myself. This game needs to be buried. Now.
Sonic 06: This game was ok but I always die when sonic runs very fast. it is equal to sonic heroes.
