I have downloaded an "Addon" for TGF2 called "DirectPlay" that will make it possible to play LAN games.
I wonder what I have to do to be able to use it in my application? Do I have to save it somewhere special?
Exactly, TGF2 is the exact same except for lack of features. That's why it's cheaper! You're not going to pay $60 for a piece of software that's the exact same as the one that's $120, and expect to get the same amount of features!
