Well Radwraith, you wanted to translate (not convert) OW to RT. I'm starting this thread, then, hoping people will chime in for suggestions. I know what I'd like to see...interesting decisions to make.
- Raising troops: feral worlders don't make good aeronautica pilots
- Outfitting troops: there needs to be a great difference between lasguns and rocks
- Training troops: you don't just hire veteran troops, sometimes they are made
- Organizing units: they are our household troops, and we should be able to organize everything from squads to armies as we wish
- Deployment methods, whether deploying from orbit or from a fortified installation or mobilization point, etc.
- Logistical limitations, maybe something as simple as supply points, or even more abstractly, combats or combat-days, weeks, or months, but nobody wants to count bullets
- Officers with personalities, and that make an impact on outcomes
- Installations and the scarcity stats to acquire them
- Non-turn-based campaign movement, maybe based on initiative, or commanding officers
- Battlefield circumstances: weather, terrain, home field advantage, scouting/recon
- Step losses: for example, if companies are the operational unit then steps = squads, if battalions then steps = platoons, etc., though squad-steps in battalions is still very doable, I just prefer the whittling down of units to the complete survival or destruction method
- Attack, defend, retreat, I want to make choices and not have everything forced upon me by the combat results; at the same time, I don't want complete control; I want to feel like everything is slipping out of my hands
I'm sure I could go on, but that's certainly enough to start with.
