that generally been my experience, 100+ hours in it starts to get slow and i start to lose interest, though i really enjoy playing the game up to that point so.
i bought the game i think about a year ago. Probably a few more months. I have 400+ hours now. It's easily my most played game aside from minecraft lol.
I've done a handful of played saves, and some multiplayer, but the game just goes too hard apparently.
