Knowing what I know now, I'd have bought in at the beginning.
I remember when the game was first announced and I saw the first demo videos from GenCon -- I said "Looks cool, but I'd better wait because these minis wargames end up being collectible, or 40k expensive, or flame out fast." So I decided to wait a bit to see how it did ... then forgot about it until I was walking through the B&N last Christmas and saw the ships on the shelf and realized I'd missed about two years.
