I wouldn't recommend pirating the games.

if you don't, and you don't do webbrowsing from inside windows then I can't imagine the need for anti-virus.

90% of attacks are trojan horses (fake/embedded pirated software usually) and the remaining 9.9% is browser attacks.

I doubt anyone is defeating your firewall/NAT box to get a direct connection to your windows machine, and even if they did they'd have to find a service they can exploit.
