As to the OPs original topic, I would also be interested to hear of any way to delay the rollout of higher levels of aliens and numbers by a month, maybe 2, as it appears to be purely time based, which is a shame. On Classic not just the strength, but also the numbers of aliens increase before its even possible to have got to laser tech level or better armour. Seems disproportionate a tad too early. Really I would like to see if eventually there is a real 'Marathon' mode, where you could double the length of the whole campaign, slow everything apart from missions down by factor of 2, so you get more of the fun Abduction/Council missions phases but less of the boring downed UFO searches.
