Thus far I have a US infantry platoon ready to go and a Soviet Motorized Platoon. What I lack is support elements for the US and any kind of Armor for either side. And of course I am doing everything in 15mm.
Romans and Early Germans are another option. I am building up a force of Roman Auxilia. I am trying to work together a set of rules for a Roman Skirmish game based on a historical Roman Cohort against a German horde. I have nothing in the way of early Germans. I do have a few Early Imperial Romans though. The idea is to have 40 figure strong Centuries. With six total centuries supported by four Turmae of cavalry. Thus far, I am a long way off. It's a long term project and its in 15mm (again).
The next thing I am interested in is cowboys. I am doing skirmish games with my son and we are having a blast. I want to make a Mexican gang but have not gotten anything. As with everything else, it is all 15mm. At the moment, everything is Peter Pig Miniatures. They have painted up quite nice.
Anyway, those are just some ideas. As you can see, I am heavily invested in one scale. Thanks for looking.
