Interesting little time killer here, where by they have recreated modern titles with a Atari/retro twist. Some of their other images are fairly funny on their main site. Enjoy.
I've always been a Sega fanboy (currently replaying back through JSR for kicks), and the guys over at Sonic Retro are partaking in an exciting project to recreate Sonic 2 in HD form, adptly to be titled Sonic 2 HD funnily enough. Over on their forums scores of fans and geeks alike are toiling hard together compiling ideas for things ranging from their versions of the soundtrack to the detail of Sonic's mouth, and the fruits of their labour thus far is very impressive as I think you will agree from this screenshot, and this video of the tech demo they have recently released. Alot more details and you can get involved if that way inclined at their forums.
There are also a couple of other Sonic projects from fanboys that have been running longer, Sonic Nexus and ProSonic.
One last thing, a plug to the now infamous Ben "Yahtzee" Croshaw. If you've not heard of him, he is a quirky video game reviewer for The Escapist. His gimmick is getting a tad tired now, but he's still tops when on form, although his older reviews are definately much improved over his newer ones which are mostly mere shadows of the former. Have a gander here. Zelda, Fable: TLC, and Assassin's Creed are among his better reviews for me.
