Can great atmosphere overshadow bad gameplay and level design?
I'm still not sure how I would answer this question at the begging, now and after another 10 hours.
Great writing, well developed characters and amazing atmosphere is not going well with repetitive missions and bland gameplay.
First two hours are great, then the games becomes so boring due to 'filler' missions and same objectives/grind which go on for the entire game (~20 hours). Its up to you to decide is it truly worth it.
