Munitions Boosters used to be my favourite; little packages of joy that were sure to increase the violence in anyone's day. They fell out of favour with me when the Fleet Starship line got its attack boost (over) buff which significantly devalued their worth (to the point of being almost pointless now).
If I want to win quickly then the
Spaceplanes see an enormous amount of use; however, I often don't want to win easily -- I like a stand-up fight from top to bottom -- so I suppose this means that Spaceplanes aren't actually a bona fide favourite. Hrm.
I really
want to like the
Space Tanks, I love the idea of a relentless drift of metal baring down on the enemy, but the trouble is they're rather, well, meh.
Currently I would have to say that
Electric Shuttles are among my favourites; they've remained fairly dependable throughout.
A fairly stochastic set of faves there such is the nature of the changing face of AI War.
