if i had nukes tech i would build a stack of bombers and nuke every opposing territory within range,
for 45 - 50 I.P.C. i could build 3 -4 bombers and nuke territories with no opposition with the superfortress tech,
getting nuke tech needs a twist because of the damage that it can do,
simply getting lucky by rolling a tech that has nukes tech combined would be a game killer, i think that a cost for nukes that would force a player to factor the cost of nukes into the I.P.C. spend would make nukes plausable within a set of house rules,
