I am in the final level(s), past the point-of-no-return* the game warns you about.
It’s amazing, folks, just amazing. I do think Psychonauts 1’s levels are overall better and more imaginitive and diverse, but this game is an outstanding sequel to it. Psychonauts 2 is game of the year material.
I am at 22 hours and I did not use guides and I also have not really fully attempted to 100% it on my own. I have meandered, wandered, searched for collectibles, but not spent too many hours scouring for every single item.
It’s longer than the first game by a bit, I’d say. Perhaps equal. I have 35 Hours in the first game just from my two playthroughs on Steam(I played it on PS2 twice as well). Then again, I knew how to beat it already when I played it on Steam.
Totally awesome game. Unfolds slowly, you don’t have all the areas and so forth right away. I would not judge it from the first 4 hours or so. It builds up more and more as it goes.
*there is an earlier point-of-no-return, but it isn’t the end-game one. I was startled thinking the game was really short, but it is just a not-so-final point-of-no-return earlier.
