I like many, dicsovered Starship Troopers Miniature Game late on, as it were and was surprised to see it dropped.
And have been picking up boxes here and there, usually items lurking on the shelves of small shops.
But I have noted, well about the uk, that several smaller miniature companies produce various alien figures, which are easy to adapt, and there are a few sets of powered armour ranges out there too in 28mm scales.
So if you cannot get hold of the original mini's there are lots of oppurtunity to proxy them. The rules, though the rule book can be a bit of pain to find specifics in, are good and it plays fast and fun. Perfect for a club night.
Infact we still have several club members playing it, and it was them that introduced me to the fun and frolics of the game.
We also occasioanly play games where a GM will run the bugs, whilst each player has a squad to command. This often leads to a rather interesting if unco-ordinated game.
So if you haven't tried SST miniature game, grab a rule book from a games show or store, plenty kicking around and give it a try.
