De Bellis Velitum (rules on Phil Barker's website)
A very nice set of skirmish rules that follow the basic DBA/HOTT format, but the figures are individually based. Looks like it might be good for some skirmishy type games (such as a castle breach, tavern fight, forest road ambush, ship boarding, town fight, etc). This could be great for typical ancient or medieval figures, or could even be expanded to cover Pirates or Musketeers.
