Some time ago I bought a couple of Caesar Miniatures boxes, Undead and Dwarves. What makes me bought them was Kings of War.
Let me explain for those who don't know this game (if any).
When I tried it, the first thing I noticed was that there's no rule for "killing miniatures", the player damages a unit but no miniature is removed, the damage points are noted down and used as bonus to test the 'Nerve' of the unit, so a unit with a lot of damages is easier to destroy than a fresh unit without wounds. If the roll of the Nerve Test is successful the entire unit is removed from the game.
1. Actually It doesn't matter how many miniatures there are in a unit, because what really matter is the measure of the unit base. I could even use a unit base that could contain 20 orcs (5"x4") and glue only 10/12 orcs on it, because no miniature is removed during the battle.
2. If no miniature is removed from the units, it could be possible use the Metric System and smaller miniatures too.
So I opted for 20mm miniatures to realize some small armies, because I think that 20mm is a good compromise solution: the miniatures are detailed even if small but they're not so small to compromise the eyesight of the players. Every miniature in a unit represents 5 models. Any measure is reduced by one half.
^The whole army
^Necromancer and Standard Bearer
^Vampire Lords and Liche King
^Wraiths and Skeleton archers
^In every miniature the original base was removed to avoid the hateful "hill effect".
In the end some good/bad things about Caesar Miniatures Undead and Dwarves:
1. Price. About £8 a box
2. Quantity. About 35+ miniatures in a single box
3. Diversity. A box includes a variety of miniatures that you can create an entire army. (Undead are better than Dwarves, there's more choice)
4. Quality. The models are quite detailed.
1. No special miniatures like cavalry, monsters, chariots, zombies, ghouls, cannons...
