Sonic Unleashed. The newest, possibly most promising looking Sonic game of recent times. With the release of the High Europe trailer, available for download on SEGA’s press FTP (600MB of full HD glory!), many views are changing about the game; some people believe it to be too linear and “on-rails,” while others believe it to be one of the best Sonic games to come out in the past 5 years. Even though, you know it hasn’t come out quite yet.

What seems to be on the down-low, though, is how many versions of the game there are, and how they differ. I’ll cover the facts right now:

There will be two core versions of the game. You have the 360 & PS3 versions, which have rich graphics and are the games showcased in the trailers available so far. They look very crisp, very speedy, and visually pleasing as a whole. Nice and solid, with quick level design and some alternate paths to keep you on your toes. Spiffy.

The game will also come out for, in addition to 360 & PS3, the Wii & PS2. Yes, you read right, the PlayStation 2. While we once thought this console had reached its slow, inevitable death, the decision was made to release a different version on the dying console and mirror it with the Wii version. The Wii version is reported to have completely different level design, but the same story and music. In addition, while the graphics are not as pretty, they still look quite solid. Check past the break for comparison screen shots!

Comparison shots have been uprooted, thanks to K2J on the forums. See for yourself how the two versions differ graphically:

The final verdict? There’s still a lot to learn about this game. But so far, it’s looking pretty awesome.
