When last did you mod a game?
I started playing one of the classic city builder games the other day, Zeus: Master of Olympus. Upon loading the game I could certainly tell that this was a game from the days of low resolution screens since the res options were betweeen 800x600 and 1024x768.
Forunately a quick glance at the GOG forum for the game led me to a widescreen mod/fix that allows you to upscale the resolution to what you desire. The game looks really good in HD and the wider view is also quite helpful.
That in mind, when last did you mod a game since we don't always get the opportunity to do so? What game was it and what did the mod do?
