A dozen characters from the show (dead or alive) could easily be playable, and sadly the only thing we’d be missing was their voicework. You could be Daryl, and have Carol and Abraham come along. You could play as Rick, and be flanked by Michonne and Carl. Hopefully more than one of them, which should certainly be possible through modding. Those are the basics for the potential mod, but I think the real magic would be in the character/companion angle, as the potential is there for modders to create pretty much any major character from The Walking Dead and allow them to follow you as traveling companions. Really, the base-building and weapon/armor mod systems are perfect for a Walking Dead game already. As the show moves into new territory, setting up supply lines and communication between settlements is great to have as well. The game's settlement building system is actually amazing for Walking Dead integration, as half the show revolves around finding a place to stay and fortifying it.
