Speaking bluntly: I have no interest in any AA product which is not strictly related to making the game easier to play. The wind indicator -- yes. Smoke clouds -- yes. T-shirts -- I have plenty of those, and know where to get others.

Put it this way: I would rather Aerodrome Accessories made available Revel Micro Wings by the case, than make a hat or shirt. One of those is usable at a con; the other, not.
