You don't need to be a Sonic fan to appreciate this game
I am not a huge fan of the Sonic series. Of course, I played the first 3 games on Mega Drive (or Genesis) but never finished any of them. The games got pretty dull for me when they became less about the speed and more about the platforming. So I was not expecting a lot from Sonic Generations. And boy, was I blown away. The game is one of the highlights of 2012 for me. It is absolutely amazing. First, it looks beautiful. You get a great sense of speed going through all the different levels from all Sonic games. Both 2D and 3D Sonic have a different feel but both control great. Also, the level design is great ! You'll have no trouble replaying the same levels over and over again, trying to get the quickest time possible by finding the most shortcuts in the level, and if almost feels like a rhythm game at some point. And you will replay the same levels several times going different ways, as there are a lot of side levels you can finish or bosses you can beat. Another excellent thing about this game is it's soundtrack. It is just absolutely amazing. Hell, I'm listening to it as I'm writing this ! There is plenty of variety, with a lot of remixed songs from previous games but also a lot of nudges to old school SEGA. The amount of talent that went into making this soundtrack is amazing in itself. I really don't know what else to say else than there are few games that I enjoyed like I enjoyed Sonic Generations. It's full of happiness and fun and awesomeness, and you don't have to be a Sonic fan to appreciate that.
