I replayed it now and I must say I found it enjoyable. The story might be predictable, but the setting is great. A post-apocalyptical world ravaged by bandits and mutants. A shooter in this setting can only be great. It has its flaws: at times it may seem a bit repetitive, but at times it has great moments. You can customise your gear, you can buy or sell whatever you want. There are tons of things that can be bought and sold.
With the money you can buy new weapons or improve your armour. You have the opportunity to shoot mutants and Authority soldiers. The guns are varied and they look great.
Overall, a great shooting in a post-apocalyptic setting.
