Pandoran Ship Size Chart.

[Suicide Junkie]

NOTE: The bases are slightly differant in size ratio to the ships. I corrected this by adding a base to ship comparison window.

I take it the troops&fighters are on a third scale all their own

Also, for some reason, I think the medium troop would be way scarier than it should be, relative to a small troop.
First, its just tall enough to accidentally kick you in the head and then stomp you into jelly as it walks. Second, its big guns are down at eye level instead of on top
