The Imperium Offtopicum "Old Guard" refers to the original core player base, roughly comprising the period between IOT 1 and Imperium Universalis. It drew primarily from Forum Games regulars, as well as a smattering of hangers-on from OT Poster Empires. The Old Guard was characterized by a penchant for roleplay-based games and open diplomacy, and was hostile toward "problem players" that treated IOT primarily as a war game; notable regulars included Mathalamus, Joecoolyo, Virote_Considon, Mad Man, Thorvald of Lym, and Double A. While a few persisted into the era of NES-esque stats games, most dropped off circa the end of 2011 at the same time the community received an influx of forumers from Civ4 Stories and Tales.
