Voted 2nd. Why?
* Lustria - Amazons with power weapons. Yeah!
* Flexible point-buy armies across all races (goblins and skellies in one army, for example)
* Scenarios: Terror of the Lichemaster, McDeath, Bloodbath at Orcs Drift etc.
* scalable from mass combat down to skirmish
3rd editions maneuvers are excellent - it's the only edition that has historicals-like tactical play, if it had an orders system it might actually pass as a serious wargame :-) Hmm. yeah, and it's not "nostalgia" it's that the game isn't so dumbed down and has an entirely different depth and philosophy.
6th is a nice ruleset (skirmish, campaigns), but army-books kill it, and it lacks the sophistication of 3rd.
