also, if you are sharing a connection via ad hoc and your computer is doing the routing and whenever the other computer does anything, it loads your bus and cpu cycles. plus, you are limited to only sharing with ONE wireless peer.

while not a big deal for net surfing, it is for gaming over the internet.

flitcroft is right, just get a router. that way, it is doing all of the work, plus the newer ones are pretty safe with spi and nat firewalls built in. I have a netgear WRT614 (802.11g) and it works great...39.99 after rebate at newegg. it also supports wpa for added safety.
