This is a set of patch rules that has been evolving among a large player-group from somewhere back in 2005, right after the release. Much of the serious errors in the game were fixed with the expansion, but it was still a long way to go. SA balances the game, increases the dynamic, making games shorter and opens for vast new number of strategies with the new unit and tech balance. It also comes with a handful pre-made maps (and following rules) that are designed for action-packed games, in high contrast to the turtling-maps provided by FFG. There's also guidelines for the fantastic strategical experience of 2-player games.
