Here is another format that is hilarious and a lot of fun.
I came up with it 2 years ago. (not to say anyone else hasn't but I haven't seen it elseware)
The Ultimate Race
A: Humans and Droids are Banned(Cyborgs count as droids)
B: Uniques are allowed Example: Logray counts as and ewok
C: Builds are of one race examples: wookiees,ewoks,nexus, rancors, etc (note: there is no faction rules)
D: Build sizes any that you want to do 150-200 are the most fun but 100 or less is quicker
E: Any maps are usable and you can play on tiles
F: 2 player game equals a skirmish style setup without a gambit zone.
G: 3 or more players roll for set up and you place in order of highest to lowest anywhere on map, or lowest to highest if playing on tiles. (when placing on maps you can place anywhere including adjacent to anyone. Most players will choose their own rooms and go from there)
H: characters that have two different races on it count as either. Example: felucian on rancor can be in either a rancor race squad or felucian race squad.(if one of the race is droid or human it is a banned piece)
J: Any at-st and most mounted weapons count as human(use your judgement) All order 66 is human. Vader is human.
I hope this makes somebody smile when played. Please let me know what you think of the game format by posting. Any question also please post.
