No . By forcing companies to make their goods is the US , they can be at least under some environmental regulation . Instead of in India and China where they don ' t care one bit . And a good economy also creates room for entrepreneurs to flourish with alternative energy sources and other possible solutions . But if you kneecap your industry and economy , you give away all control you might have had nor is your country in a good shape to weather it ' s challenges . <| sep |> Hangry Batman ! But also what uPopHunter 427 said <| sep |> Story wise it ' s Sky , Land and then Sea . All things you unlock in the DLCs can also be used in the main game . The jetpack wingsuite you get soon after starting the Sky Fortress DLC is quite a game changer , so I ' d recommend if want to master the normal wingsuit before you get the new one , start with another one . But than again you can also just change back to the normal one in the options if you wish to do so . You will have to play the mission A terrible Reaction before you can start the DLC missions . Should be the 4 th or 5 th mission . I would recommend playing the normal game for a bit before starting the DLC mission . Maybe after you leave the first island ? But that ' s up to you .
