So, I think I blogged about Stratagus a long time ago. It was an RTS engine that was ported to Amiga OS4 (and possibly 3.x as well). Using some addons, called Stargus, Amiga users could play Starcraft 1. It’s been around for a while but there is something called Wargus for Stratagus that makes Warcraft 2 available for Stratagus.

For the adventurous, you should download Stratagus first:
