For the last few weeks Pawel and I have been playing the odd test game using the Sci-fi Commander rules. These are a variant of the Blitzkrieg/Cold War Commander rules that Pete from The Wargames Directory is working on.
The rules are interesting in that they are at once more complex and yet less complex than Epic:Armageddon. The units have fewer stats are are far more generic than they are in Epic but at the same time the ruleset has more options available to gamers making it more tactically interesting that Epic.
Unlike Epic unit are bought individually and there are no limits except on Recce units, artillery and heavy tanks. So if you want you can build an Eldar army with nothing but Aspect Warriors. As well the game comes with a system to allow you to create point costs for units so you can use it with any miniatures you have available.
One of the better aspects of the game is that artillery has on-board and off-board options, smoke and concentrated and barrage firing options.
The game also has rules for Recce units, snipers and very good orbital bombardment and airdrop rules
About the only thing that it doesn’t have is the Epic:Armageddon GT scenario which is pretty easy to port over :-)
