Well, as usual I've been asking for things like that for some time.
In fact, I've asked for just about everything in MOO or MOO II at one time or another.
The 'Engine Pulsar' that sends out a wave of damage in all directions around a ship would be very cool. The 'Lightning Field' that has a fixed percent chance to fry any missile before it hits your ship would also be very cool. I've also been thinking about some "original" stuff but wonder how hard it would be to program. Like, a "web" of some sort, like the Tholian web thing from Star Trek, that you could "draw" on the battle grid and ships would have to take some huge amount of damage to go through it. Yes, we players can imagine all sorts of cool things. Poor Aaron would be chained to his keyboad for decades trying to program it all.
I'll be happy if he just implements the stuff he originally committed to, like drones and warp gates.
