PA has very little micro. But it is early.
They are releasing a big update sometime this week that is going to add units and overhaul current balance. Along with unit teleporters and UI changes/additions
PA price will be 40USD on release. DRM free, and will include a boxed version.

Adjacency bonus in supcom added no strategic depth IMO. It added complexity for no reason.
There were no options, you either new how they worked and used them, or didn’t and lost. Period. It was very unituitive and a detriment to the game. Regardless of how good it may sound on paper, it was very poorly implemented and the devs made a wise decision to not include them in future games.

I will admit that supcom2 release was rushed, but most if not almost all of the complaints: reasons people disliked it were adjusted:changed not long after release in patches.
It is not fair to criticize the devs for this, the same as it is not fair to criticize LH for the flaws in 1914. I doubt any good dev wants to rush a release at the expense of quality.
