so in this game you either
>play the career campaign mode and savescum around 7 times a minute
>play sandbox which is a fulfilling yet tedious experience
>play the game after taking half a day to install a ton of mods for the perfect experience (which will last a few hours until it breaks completely or you realize the game is pretty much the same)
or
>play multiplayer (which is very fun) after waiting weeks for anon to start hosting again
