I have 2 large 1:300 armies made up of H&R figures, Late Imperial Roman, and Gallic. I made these a long time ago, in the old WRG 5th/6th Edition times.
At the time I went against the rules and based them in 20mm base widths, with larger scales number of figures, so in practice this amount to half-sized 15mm bases with the same number of figures. The upshot is that instead of having normal size tables with a sea of figures, I can play in a coffee table with the smaller 15mm amount of figures, allowing me to play an entire game with no need to raise my butt other than going for another beer
Economy of space and cost, and increase in comfort. I know the rules do not cover this, but as I don't really force anybody to play with me no harm is done to the community. So with my 1:300 (I play in 15mm as well) I'm going with 20mm width bases, 15mm number of figures, and UMs will be 1/2". I suppose there is no objection to this, any comments?
I will start this week playing a few solo FoG games with my tinies, as at present I'm living in a small city with no opponents nearby.
Cheers!
Miguel
