... in my opinion some hints don't hurt. ... it is more about guiding player to understand the game dynamics better.
While that's true - and Solarius is indeed not against it and has even provided a whole Field Manual's worth of hints - learning that some aliens explode (or have melee reactions, or whatever) looks very much like something that is done via trial and error. That's the theme of both OG X-Com and the Files - you're fighting an unknown enemy with unknown capabilities.
If you have other suggestions, I'm sure Solarius will listen.
... I also bioextracted my live x-com squad candidate shadowbats
I don't think there's a good way to avoid that via mod internals, so you have to manage this yourself. Put your Shadowbat recruits into a different base, maybe.
It is impossible to shoot down anything, because I hardly had one little bird as interceptor in that date.
Hmm, it's the second time someone complainins about early retaliations now. Curious.
Maybe I need to make it clear that I am not against the reinforcement system, only the way it works. ... Similar approach can make the game more realistic.
Well, as Solarius said, the reinforcements have to come from
somewhere, and there's no good way to make sure that this somewhere isn't a death trap for players. Well, unless they spawn in some bunker/craft of their own, which makes the whole thing kinda exploitable.
And, IMO big neon arrows pointing out enemy reinforcements are very much gamey and the opposite of
realistic.
But I already put my intended character to the top but it didn't work, the game selected it randomly.
This is strange. Do you perhaps have a save for this? Because as far as I can tell, it's indeed the top unit and not some random dog or rat who gets selected.
