Yeah, count me in as one of the few that didn't understand the hype. CD Projekt Red seem like a great group of devs who understand what people want (free DLC and even a thank you note in the game, nice touch). I didn't really like the combat, upgrading and leveling up felt too much of a slug, side missions' length felt poorly judged and the characters were unlikable.
Happy to admit I'm in the few though. Sold my copy after keeping at it for two weeks.
Think the point is that it's too sparse. Fallout is post-apocalyptic but it's full of varying content.
