Hey, remember last generation when Xbox 360 multiplats were better forcing the PS3 to be discontinued and Sony out of the game console business?
We're now getting onto our fifth installment of this feature, and with every passing year the differences between the consoles continue to melt away. When we first started this feature, the differences between some versions of games were astounding. Fight Night Round 3 looked drastically better on the Xbox 360 with its improved lighting and shadowing effects. The following year, the graphics on both platforms got considerably more even--Oblivion even looked better on the PlayStation 3. Every subsequent comparison pretty much ended the same, with the Xbox 360 getting the benefit of slightly higher-resolution textures and other marginal improvements that wouldn't be noticed unless the images were put side by side. We'll see if the trend holds true with some of the best games from this year.
Assassins Creed II continues the trend we've seen with the Xbox 360 getting marginally better textures. You can see a bit more detail in Desmond's jeans, and the number 2 is considerably more clear in the Xbox shot. The Xbox 360 might also benefit from normal mapping, which gives the floor surfaces, the brick lines, and the door rivets a more 3D look.
