I used to hate early access - why should we pay to test an unfinished game, when that's an actual job that people get paid to do?
but I've come to recognise that it's am important avenue for funding for many developers, and tbh, I don't think any of the early access games I've played have felt "incomplete" - perhaps lacking polish, perhaps in need of more content, but that's true of many full releases, and early access not only gets you these games at a reduced price, it effectively guarantees a large amount of free DLC as the game gets made more complete.
my only real complaint now is sometimes I like early access features which end up getting cut from the finished game.
