Radar's articles are great; the whole blog is excellent reading for ECW war gamers.
As CB and VF stated
Pikeman's Lament is very enjoyable and sounds like it is the "size" of game you are looking for. Besides PL I have played a number of different systems in the last few years including
Pike and Shotte,
Victory Without Quarter,
Warr Without An Enemie,
Carnage and Glory II and yesterday a large 'skirmish' using West End Games
Star Wars Miniatures Battles- weird but true
. So ... perhaps you shouldn't take my advice too seriously then...
