I think Mod Tools & Mod Support (Steam Workshop) would add so much to the game and not only give the fans of Mafia III more content and features they thought were lacking, but keep a lot of longevity and gameplay to a game we might have a long wait for a squeal. Look at the success of other games with large modding communities.

Examples:

Skyrim Fallout 3 & 4 Civilization IV & V (And now VI has mods) Witcher III Minecraft Mount & Blade The Sims 2/3/4 ArmA II & III Half-Life 2 (The game that never dies.) S.T.A.L.K.E.R.

These games have endless amounts of content to keep people playing, and to get new players. I hope that Hanger 13 and 2k see this and decide to add themselves to the list! (PLEASE SHARE THIS PETITION!)
