So I am making a zombie game(rare isn't it!) anyway, but what I am doing is trying to allow players to do something that other zombie games on here don't do(at least I have not seen any). I am trying to make it so the player goes through the main story, but also has base that they return to at the end of a mission and here they will be able to purchase survivors using daily supplies they find out scavenging. They can also use these to expand their camp and at the end of the day they will lose supplies that are used to support the survivors they have. The player will also get a certain amount of supplies based on the number of players they have because there is crafting in this game. So for all of you that have played the Last of Us online that is what I am trying to follow, but of course have a different storyline. Any advice, or if you think it is a good idea, or if it is terrible.
