Epico is an evolution of the core Renatio et Gloriam rules to allow streamlined play.
It came about as Warlord Games released their Epic range of miniatures. Epico also allows 28mm play on a smaller table without the need to reduce the size of TUGs.
The streamlined nature of the rules means that Epico is great for teaching new players.
The modifications are in Draft format – attached here
