I'm looking for a good solid sci-fi ruleset that's not tied to any specific line of miniatures. Good for larger skirmishes and small battles... nothing for massive battles, but more then 15 to 20 guys a side. One that's similar to a lion rampant or a dragon rampant ruleset where it just gives me a good outline of rules along with several different Army lists and factions. Mostly just a good solid ruleset. I have a lot of different sci-fi type Miniatures that I'd love to create my own warbands with and add or subtract weapons or Powers as the rules would allow and just have a good battle. Needs to have thought through troops, artillery, and vehicles (mechs, walkers, land speeders, and 40k style tanks, as well as air craft will be used.... human and alien on all accounts).... something adaptable to these conditions... i don't mind having to do custom specs for some of the areas it doesn't hit... i.e. troops, heroes, and tanks but not artillery or air ships... I can adapt....Thoughts??
