Another game which, going by the quality of the trailer alone you understand, is quickly gaining esteem and appreciation in my eyes is the post-apocalyptic survival game The Last of Us by Naughty Dog Studios. Apparently the game is going to be a far more realistic approach to post-apocalyptic survival horror in that you have to to struggle for every resource you can find to try and make it through the game. And that strikes me as not only intriguing but definitely worth following.
The trailer helps matters along by (as is standard for trailers these days, it would seem) being absolutely awesome!
