Great unit AAglo, and perfect for the "Titan" summon in my FF mod. Basically, all summoned creatures will be available through small wonders that require a game specific tech (i.e. all FF VII civs (Shinra & AVALANCHE) would have the "Summon Materia" tech, but not any of the civs from the other games, whereas the Final Fantasy VIII civs (Galbadia, Estar and Garden) will have a "Guardian Forces" tech that allows their small wonder/summoned creature that none of the other civs will, etc.)
It goes without saying for Final Fantasy fans, but for those who are unfamilliar with the series, the Summons will all be most wickedly powerful creatures.
