it was 100% obsidians fault. they agreed to the time, and they yet again were way too ambitious, like with kotor 2. its just who obsidian is, bad time management and bad ambition management. they do make great games but those are 2 real flaws they have
theres no way you can see the detailed world and say thats zero effort. its like the best world bethesda has ever crafted. its huge, vaired, and interesting. regardless of the games own failings, its definitely not a zero effort release, otherwise they would have given up on it years ago
