OK, who's been getting into dad's liquor cabinet?
If we have this here, how about these little things to keep gameplay interesting:
I say that for all the allies within blast range, not only do they die, but the B-29 pilot gets a killshooter penalty ...one hour per allies you vaporize, including any drone troops, supply drones, and the like. Add to that, 24 hours per friendly base that also gets vaporized or falls within the radiation field, that I am sure HiTech just can't wait to model, and remodel, and remodel....
Not to mention all the perks you would lose for dropping and not landing safely (dropping the A-bomb at high alt still produced a pretty nasty shockwave), and all the perks your allies lost from being killed in the blast while in their perked vehicles / planes.
If you want to have that type of firepower, then let's set up a series of penalties, arena-wide, so we can get some clue as to how senseless it would be to bring this into a game.
I may be wrong, but I doubt it
