Yeah, I am happy to wait. I've bought plenty of Early Access, Beta access etc type games and, on the whole, they have been disappointing with the exception of Kerbal Space Program
Project Zomboid has been worth every cent + 1000% more. If they never released I already played enough hours to justify the purchase many times over......
But I do get peoples concerns. With the phase 3 release of the Master of Orion reboot I'm having alot of fun....not so much with the first two phases.
In a sense it's probably better to have a firm vision rather than listening to everyone's constant feedback. A closed BETA on the other hand could be good for bug hunting.
