Many practices of gamedevs - like designers literally just exploring stuff without any plan for years before commiting to any feature - would make SV directors and PMs (not to mention investors) scream. :) This is a double edged sword. On the one hand, this aimless exploration is needed in pursuit of real fun (as opposed to compulsive loops of mobile games). On the other hand, this leads to crunch, games being buggy and always delayed, and how most fun games always had very troubled production and sometimes literally destroy the studios/teams.
More organized companies I worked at (Ubisoft) had less crunch but also less fun games (cookie cutter AC formula). The messy toxic crunch workplaces (CD Projekt Red) I was at produced amazingly fun cult games...
