Okay, so I was browsing teh interwebz like I tend to do when I get bored and Fallout New Vegas gets buggy when I stumbled upon this, some group of awesome people went and remade the first three levels of Sonic the Hedgehog 2 for PC using the Unity engine. The results are Amazing!
Below I have provided a link to the site where you can download this amazing demo of one of the coolest fangame projects ever, I hope this one stays alive.
They did a really nice job, that engine is something else. I’m acutually able to play it. I have a PC and a Mac now, they bite eachother sometimes, but in general they’re friends.
