Anybody remember Worms: Armageddon? THE party game of my middle school days.
This is not a party game (well, it can be, though). I have a friend at college, we played W:A religiously and very competitively . We actually started playing for "money" (it was only to boost competition, small amount of 0.5$ per game at the end of the month).
Thing is, at one point, it went from just playing Worms to plain hacking.
First, my friend has made a program that, when run before each match, it would shuffle his team members so that I do not know the order of the worms. Now, to counter that, as we played on Hamachi (fake lan) and he didn't protect his file-sharing settings right, I managed to get in and steal the info about teams that program made for him..
To counter it, I've made loads of different teams so each he had to start writing them down anew (was lazy to code anything).
Next step was that I manage to scrap replays that are created real-time to get this info, and he started sniffing packages that I send to get the same info.
At that time we kinda decided that we should stop with at as it was getting ridiculous .
He is still in the lead with some small difference of 5 games, tho we haven't played it for a year or two.
