Tha main reason is in the change to low-poly is we had the opportunity to by these type of assets. a lot. Thus, we have the opportunity to build a coherent but diverse world from it. We are two programmer/game designer without 3d modeller in the team, so we are working from what we can get :)
The overall quality will be much higher than it was in NeonCode1. At least... this is the plan :D
