OCD with the Letters in the Right Order!
My Attack! Deluxe ships are blue like my base game. My base game units are blue. Wonder if they had some off color runs.
Both my base games had purple land units. They are much older copies though. Their site shows both colors, so they may have changed the color in the base game at some point.
Still annoying that I have to buy $75 worth of stuff or pay $23 or so for proper matching sets.
