The soon-to-be Game of the Year 2013 hasn't even been released yet but if Rockstar hit even half of the features/abilities they are promising then it would still win. With the journalists getting to finally see the game run on a console and still say that it looked impressive I have full faith that the end product will be incredible.
However, I simply can not figure out how they are making this awesome of a game on 7+ year old hardware with only 512MB of RAM! I honestly don't even know what to expect for the next GTA that is fully developed with next generation hardware in mind. Massive disk space, massive HDD, and 8GB of RAM can only lead to amazement. But, the current year is only 2013 and I must suffer with this masterpiece from Rockstar this fall.
