I don't honestly understand why this is a big deal.
As of Cats & Dogs, PC requirements went up then as well, from 2gb of ram to 4gb of ram. I know this because my PC only went up to 4gb, and would crash the game constantly since 4gb is actually 3.7somethingsomething because the OS needs some too. To be fair, that computer was 10 years old (that's like 200+ years old in PC time), so it was time to upgrade. Even that old dinosaur supported Windows 7 64bit, so it's just a matter of an upgrade to the OS in many cases, which isn't that expensive.
