Hello everyone!

I've known about this game for a while now, however as I was in college and pretty busy I never bought the game. I now find myself with free time, and I randomly remembered this game. I decided to check if there were any speedruns for it, however I am not sure what to get into. If possible, could someone guide me on all the different categories, and if you are ok with 100% runs taking multiple sessions (For example- spending an hour 10 mins, logging off, and then continuing another day from that save until the game is over)

Many Thanks :)
