...is it important to make sure to share them due to this or is it not as important as it sounds? I am guessing looking at the wiki it's just due to 1 or 2 more missions but are those important to get?
The converse, you get some horrible 'slander' missions that are nearly impossible to reach due to how quickly they vanish, and tank your score (-500 a pop). Plus a few score-lowering pop-up events.
So far I've only had 2 options to share, I have shared Tritanium and am currently trying to make the decision for selling Sonic technology as the weapons sound nice but the instant money now sounds better?
Money is ultimately not a problem, even $5M. Missing a weapon tech is not really, either, but it's more unique. But this is an actual dilemma, and I don't think one of them is automatically much better than the other at that particular point. If you're a collector, want to try out the sonic guns or just like to use them, go for sharing. If your game could use a boost
right now, take the money.
I have seen there is some good looking stuff for sharing the other technology but not sure what is or isn't worth it.
But of course since this is XCOM I'm probably going to share everything since what are morals?
Eh, X-Com is all about morals. The human morals of 'We will
not be alien cattle!'. Or 'Illuminati cattle'.
What's the point, otherwise? And it's not as if far worse things are already not running around thanks to the NWO just sitting on their asses all day.
