anyone getting sick of nukes?

That's exactly what TA did. Units could shoot at nearly anything, and any hit counts. Nukes were a rare exception for the game, one more likely based in engine restrictions than based in terms of gameplay.

Let everything possible take a pot shot at the nuke. If enough guys land a blow, they kill the missile and it goes boom. Therefore, large base flattening power becomes less game ending as the nuke can't pierce a full base's defense. Simple mechanic, complex outcome. EZPZ.
