POLL: Best Toolbox Rules (Round 1A)

 John the OFM  writes:

The Sword and the Flame has well established and deserved reputation as a "toolbox set of rules". In other words, the basic mechanics are not really "period specific". I've used it for FIW and AWI games with very few changes. Obviously, rifles are very scarce in both, despite the prevalent mythology. So, use Carbine ranges. Are Grenadiers and Highlanders superior? If you want them to be, you can give them a +1 if you wish. I just call them Regulars who think highly of themselves. Do what you want! Or as Johnny Ringo said to Doc Holliday, "Age quod agis". Add bows? Sure. Why not. If you're fluent with the rules, you know what to do. There are 3 flavors of Native troops. Choose one, or make up your own.

But I would like to recommend another set if rules that can be considered "toolbox", and that's GASLIGHT. I've used it quite successfully for "small unit" skirmishes. Last of the Mohicans, for one. I have had Sasquatch controlled by a Lakota shaman. Even strangers at a convention accepted that with no complaint.I've run Wyoming Massacre games using both rules, with small modifications.

I'm throwing this open to the Hivemind Mib. What other rules would you recommend as "toolbox rules" that are adaptable for out-of-period play, with very few mods?
