I'm glad Sega is finally making an effort on its PC ports. I was especially impressed with the dust trail particle effect the minecart produces. Really well done, seems straight out of CryEngine 3.
Man, I really should have entered this into SAGE this year. I just played all the games there and this is easily better than half of them. I could have even made a fake Sonic Worlds splash screen and everything.
Turns out the download links in the op were broken so I took it upon myself to fix them. I also posted a video of someone's leaked Episode 2 footage in the episode one thread in General Sonic Discussion but it seems to have been deleted by a certain person. The guy on Youtube says he'll be uploading more videos, so if you're on a Mac or don't want to download an awesome game, you can see how the beta plays.
