The terrain transparency issue is something certainly worth having a look at, I'll put it on my list of things to do.
I still also want to re-redo hitpoint values and weapon DPS. But what I would really love to do would be to look at the relationship between hovers and jets, as well as taking a look at fins.
Imo hovers should work more like a generic ducted fan, rather than being an antigravity device. Adding in of some sort of 'ground effect' (if the fan is pointed at a solid surface, and the surface is within a certain range, it gets an boost to thrust output) vectored thrust (rather than thrust always opposite to the force of gravity) and possibly making them reversible. Also gravity-based efficiency for hovers, jets and fins. With hovers and fins losing effective thrust as the gravity drops until they provide zero thrust in zero gravity, and jets effectively being the opposite, with poor thrust ability at 'normal' (10) gravity and having the thrust ramp up as the gravity drops.
A guy can dream right?
