Many gamers look at 2007 as the best gaming year of this generation. Lots of great franchises were born. Bioshock, Mass Effect, Assassins Creed, Dirt, etc. Then you also had the Orange Box, Halo 3 and COD 4 release that year, and Gears of War 1 still in it's prime. The reason I say 2015 is because it's 2 years after the NextBox comes out, just like 2007 was 2 years after the 360 came out, and seems to be the about the time that developers really start to tap into the new consoles potential.
So do you think that 2015 could match 2007 and will the beginning of the next generation take away the staleness and put some excitement back into gaming?
