Yes scratch building 100+ miniatures is probably a bit excessive. I seriously reached my limit with this project, but whatever period or scale you are into this hobby looks so much better "en masse".
But I also say with a little creative thinking any gamer can put a horde together and most importantly without it costing the earth.
For projects like this I turn to two sources. Ebay and my local pound/dollar store. For the robots I put in seraches to Ebay like "100pcs" and glanced through the results.
That's how the robots bodies ended up as 'plastic panel rivets' (or clips for the beetlebots) and the legs are 'jack plug dust covers' which is something I never knew existed!
While doing those searches I came across a number of other useful items, searches for 'party bags' brought up very cheap toys including spaceships, cars etc which could all be used in some form or another.
If you are willing to wait three to four weeks then a whole range of plastic bits and pieces can be got from Chinese suppliers for £0.99 including postage.
I think for next years project I will look to do something a bit different, no I won't be able to resist having lots! But I will try and avoid total scratchbuilds.
Thanks for all your comments. I am still planning on creating a little trailer for the game and of course will take pictures and report back on the game when it is played.
For those of you who would like to see it in the flesh it will be at the Maidstone Wargames Society open day,
details here.
Cheers
