My two cents....
Got into UA:D mid 2020 and i see the 50 bucks more like a kickstarter pledge. I like the game, i wanted to support the dev team in their work so i got the Limited Edition. On top of that i can influence the developement process via bug report or forum feedback.
Sure, the game still has issues and a long developement process, but i know what the covid chaos did to my field of work.... and i work for an hydraulics manufacturer with 10k employees, not some small dev team.
So far i enjoyed random battles and academy a lot and liked my first run at the campaign, KNOWING that it is a barebone mission generator atm.
