... are you seriously that incapable of imagining other situations than your own? It's entirely possible for people to post to a forum using an office machine, a netcafe, a library computer, etc, and still not have a home internet connection. It's entirely possible for people to post to a forum using dialup that they only connect for an hour a day. In both of these situations, no, they would not have enough bandwidth to activate their single-player game every single time they wanted to play it. (With dialup you can easily activate it on INSTALL.) Stretch your head a little.
