I've been playing this on and off since about 2011. The rules are neat and simple and quick to learn, giving a fun filled 30 minutes or so. But while they are simple, the "AI" you fight againgst still has a decent chance of beating you. Also, as others have found, because the rules refers to to units rather than actual numbers of figures, things can be scaled up for real massed battles or down to single figure level *
I bought the expansion packs for this and Chronicles of Arax more out of support/appreciation for Shane Garvey's work than necessity. I also fell it is shame that despite initial enthusiasm, back in 2011-12, there is no real community or continuity for this game, as I think it is a great intro to wargaming for busy folk or with children or just anyone really.
- Because of this, I have just started scribbling up some "house rules" for "Chronicles of Vacuum!", that replaces regiments with space ships. (If anyone is interested...)
