can someone make a mod where a game can last longer on the market for example how WOW is still selling after 10.5 years and also can you add something like we can update a game(not mmo) as many times as we want and have the game last long and have players online on it.
Thanks. 
P.S. If their is such a mod leave a link please.
WOW is a MMO.
WOW is a MMO (Massive multiplayer online) they add expansion packs which brings back sales and interests new people by having it add new things or change things completely.
They have free trails that get you hooked and then you buy the game, and possibly its expansion packs.
But I get what your saying, you don’t want to have to make an MMO game you want to be able to add updates to the normal game not sequels. But in real life updates don’t really change games that much to were sales come back. You’d need something more like expansion packs which there are games with them created outside of MMO games with expansion packs. Command and conquer generals, Sim City, Command and conquer, Warcraft 1,2, and 3, Starcraft, Starcraft 2 and so on.
yeah I want to be able to add dlc to a game any suggestions?
Unfortunately I don’t know of any mods that does that. I thought I did but I can’t seem to remember what it was if there was one. I’d recommend finding an active modder who knows what he/she is doing to make this mod. It isn’t to complicated.
If it wasn’t, it would have been made by now.
