Well, they get the snuff out competition and get to hold on to IPs. The thing is though: People are saying that there are good indie games, but I won't ever hear shit about said games unless I specifically go looking for them, which will almost never happen nowadays.
Even when I allow ads, game ads are pretty rare. AAA games were almost impossible to miss because there's always enough buzz, positive or negative, for the big ones.

I make sure any motherboard I buy has at least 8 USB ports, so I know I'll have enough. It does make sense to use the PS/2 port if you have the peripherals. What advantage does USB have over it anyway?
