ahh Pf1,
Interesting take if I must say myself that probably the burnout from the playtest is really what might be shining through. These really are probably how at least half the player base is feeling as I would say you are one of the lucky ones being able to see that game before its current state. -note: backend developers are probably currently unaware of what happened in the first place with them early on.
Not sure from not having really been a part of the big wave of early access titles over these latest decades but the game is in a state where if you are looking for the game hunter type achievements, then I'm not sure here. It does seem like when it comes to scratching the surface of the game, you have absolutely beat the game in a sense.
From a progressions standpoint most people at this point probably couldn't even comprehend the amount of sheer reliable advice you could give from all the testing, but I didn't really give the playtest full reliability testing but did some minor improvability functions from a mechanical standpoint of input devices and such.
Sounds like you might put it on the shelf and see if maybe you can dust it off sometime or maybe watch some gameplay until you see that it meets what you have seen in the testing period. glhf
Cheers, KF
