Considering how long this game, you'll be able to blow through the story mode, whore mode and finding places to customize your character. Not only that, you'll be travelling all over Steel Port finding gang areas, buying shops and apartments and participating in minigames.
There will be important places in the story mode where you have to choose which one you want to be rewarded with. Like automatically acquiring land or to boost your income every hour. Also in reputation levelling, you must upgrade yourself throughout so you can say, be immune to bullets or sprint non stop.
Lastly, if there's any difference between consoles in terms of content, there will be places where you have to go through those challenges like taking on a big muscle man or collecting items around the map. There's no stopping you so go for it. The Saints are counting on you!
