They give out updates regulary with a considerably high quality compared to many other early access games i have purchased. Unlike most early access the current state at each update could be the last and i would still consider it a great game. Sure its not done, there is faults but in the end they have delivered exactly what the said they would, a work in progress. I will only be disappointed if they say they are done without completing the scope they have planned. Fortunatly so far i seen nothing but they increasing the scope with new features that was not initialy in the plan. The release model with prerelease qa on each update probably take a huge amount of time they could have spent on adding features and parts but i rather have something polished to play with while they work instead of a barely working normal alpha or beta.
