Im sure the best thing to sell is alloys, although i ran across a different thing not too long ago, i manufactures a few mind probes when i was short, they DID sell for alot more than purchased but i only tried it once and never really looked into it, alloys are just too handy to have on the side anyways.
Heres a Q i been thinking on for a while, never really tried it out much in play. The cyberdisks explode when killed as we all know, when i 1st played this game on playstation i remember taking a few of these things alive, but on this version even when hit with stun bombs they explode and when i tried a stun rod just for something differrent the damn thing blew in my face!

So .... is it possible to capture a cyberdisk alive? or have i just been unlucky to not get one alive in the 300 odd battles ive fought?
Another Q: when aliens are on the interdict mission converting countries to go against X-com, when is the critical agreement between the two made?
1. As soon as the enemy craft departs for its mission.
2. As the enemy craft lands at the destination country.
3. As the enemy craft sits in the destination country.
4. Before the enemy craft departs from the target country.
5. As soon as the enemy craft lands at base
My guess is 5 but im still not convinced, if i blast the craft down before it makes it to base, is the aliens agreement void? or is the agreement sealed before the craft takes off?
Another thing, does blasting the craft down cancel the agreement? or do i have to go down and kill every alien? AND if there are 3 enemy craft at the country all different sizes, and different races, do i make a certain race/size ship my priority? example .... will a small craft full of etherials with thier mind powers do more persausive damage than a very large ship full of snakemen? or are all ships equally damaging at interdiction?
Not sure if any of this info is even possible but im interested to see if anyone has some facts.
