The world record for 2.0+ standard currently sits at 2h56m14s. Glitchless has no 2.0+ submitted still, but the pre-2.0 record is 3h12m10s. So it should be plenty doable if someone just wants to run through the main game and some side stuff.
Now 100% while it's free would probably be interesting without the knowledge of glitches that would speed things up.
I spent 112 hours to complete the game 100%, that was my first play through so I listened to all the dialogue and took things slowly. I think it might be possible within 48 hours
Being from North West of England I felt this. Shit, I'm still looking forward to this dialup tone people are nostalgic for. We get our Internet via pigeons at the moment.
