I played Sins of a Solar Empire pretty much just for the interplanetary cannons. I have some very fond memories of those things. Even if they work like Sins where the bullets travel slowly and give the AI time to evacuate, I will still be stoked.
...Really want a Longgunner of the Apocalypse-style weapon that targets specific structures on a distant planet, though... ~wonders if anyone will get that reference~ ~related: headcanon name for the Very Large Ion Cannon Array is def going to be the Very Dangerous Array~
