You’re in for a treat! The game is a literal rabbit hole. The more you play, the more it opens up. I think I’m close to a hundred hours in and my start menu is very different to where you’re at.
It’s literally a self-bought gift which keeps on giving! I’m finally getting close to unlocking everything.
Have fun! I wrote in that other message I was close to unlocking everything, right? Well, nope! Fulfilling a certain secret led me to unlock more secrets to fulfill! The rabbithole, goes on and on.
And yeah, all the DLC are great IMO.
