" Has their communication at times been lacking?"
" Has their communication been lacking?"
A) These are not the same sentence.
B) Yes, based on what they have shown it's exceptionally commendable. They have an engine which can handle large numbers of NPCs at once, handling relatively in depth AI, an excellent physics model, all while looking pretty good and running smoothly. Go drop down 200 guys in ArmA and tell me how well it runs.
C) Doom (2016) Took 9 years to develop. Rage took 7 years to develop. Team Fortress 2 took 9 years. There are plenty of great games that had lengthy development cycles. But those are AAA examples, and mostly weren't also forced to create an extremely specialized engine. You can say it's unusual to take quite this long. But don't start talking in absolutes like it's just a fact.
D) By what accounts do they not have stable build? I never got that impression from the Gamescom videos. That simply means they're not adopting the "publish now, fix later" mindset that is a PLAGUE on the game industry.
E) A lot of games suffer from crunch time. I remember from way back when, when they had a photo from their company cookout. That tells me that Taleworlds is a company that values its employees. And if a company has slower development because it values its employees, that's a good thing. Period.
