Of course you do. Other than the people of Jericho, everybody does. Well, Fallout, Fallout 2, and Fallout Tactics are all free on gog.com right now. Their secure server must be on fire, but keep at it. It didn't take too long for me to get them purchased.
Edit: Also, I don't know thing one about Tactics, except that it was free. Anyone have any thoughts on it?
