I don't know what anyone else thinks but I really do get irked when game vendors do not give you a content complete game on a given platform... I was ticked when I heard Gears of War for PC has more then on the 360, I was ticked when I heard that 360 was going to have less UT3 maps then PS3, and now I'm ticked that PS3 won't have as many UT3 maps as the PC...

I am alright with vendors using the extra features that are unique to each system, like XBox Live!, PS3 Cell Procesing, Wii motion control etc. But, in general every game should have all of the content on all the platforms. The experience can be different per platform (More online, better graphics, cooler controls, swapping discs, etc.) but you should not be content deprived.
What do you think? This is a trend that seems to be gaining momentum and I don't like it one bit no matter which platform you own.
