Thanks for the comments!

It was real fun doing

It seems that I should clean breath/lips (or how that sound engineering jargon should be translated in English?) before final version (audible some times even under music). I will add exciter to the voice (for mixes I used the exciter at final mastering stage so it is not in the 'clean' file yet).
I can do it only tomorrow, urgent need to write some music today

I had to do it a week ago, and so I've got only one night left
Should I split them into phrases (they are just a single chunk now)?
I've made it at studio quality 48Khz/32 bit. Which format should I use? I can convert it to standard 44100/16 bit.
Should I use WAV files? Or compress as max-quality OGG?
Should I include some reverb in the file as in the mixes? Its sounds much better with reverb, but reverb usually should be 'equal' to all the scene events or else it would be not natural.
I also experimented with different processing. Should I also upload some more processing variants? I think they are worse.
On the other hand, there are several pops and clips, I've masked those, but still audible.
Moreover, there were suggestions on the script. Maybe we should first make the corrections?
I'll be able to record again after mid January. Too much preparations for the winter camp and finishing projects at work. I need a chunk of ~1 hour for recording and ~2 hours for processing the same amount of audio (however, this time it will be much less experimenting).
So there is still time to make some more text... maybe like campaign briefing / campaign relative text&comments.
It is much easier to record '
more' and 'cut' something, than to
add something later (It is sometimes hard to preform the same feeling another day and the role may sound not 'homogeneous' between phrases, added chunk also would need identical processing which parameters I sometimes forget to save after experimenting).
On third hand I thought that it would be fine to test the voice in-game before the re-recording. Sometimes it gives good ideas. Like add text for 'building completed' even when it doesn't take time to build. To make something shorter/longer.
I'd advise CC-BY or even CC-BY-SA 3.0 so you officially keep authorship of your work.
Ok, let that be CC-BY-SA 3.0. However, I have absolutely nothing against CC-BY 3.0 or OGA-BY 3.0, so I take any advice on that

The two keepers are great, I especially like the groan one
The groan one was the hardest

But it definitely sounds much more horrible after processing

I was worrying about text audibility at the end of phrases.
