I'm about 10 hours in and for the most part it's been bug/glitch free. I've had a few graphical bugs during parkour, and I've managed to hang with one arm from a kitchen table, and parkour my way to the top of said table.
Voice acting and story are great, but I'm unsure of just how much of a difference my choices in the game are actually making.
If you liked the first game, I'm pretty sure you'll like this one even more.
I'm loving it so far.
