What is the longest session you've just sat down and played either 1 or 2?

For me it has to be about 3 hours of number 1. I sat down and finished the first 3 scenarios way back when as a child... now that I think about it... I've never beat it before...

Yup!! The years requisite makes it longer to beat some, but woah, in the good old days, I used to play a lot! Sometimes for about 8-12 hours straight, making the park of my dreams :P Now I just found GOG and bought the 3 games with this winter sale! Time to get some fun again! and finish the damn scenarios hahaa

No sorry lol, I meant I've put in 3 hours since I've got the game (much more now) and I love... than new thought path, when I was a kid I only did the first 3 scenarios. They were separate lol, sorry :P

When I was a kid I would play for hours sometimes in chunks of 4 or 5 at a time. I also spent a lot of time watching my dad play it and would try and steal his ideas for my own park lol. Never worked out well.

Funny thing after I bought the game when it went on sale my dad was visiting me and watched me play it and remembered it from all those years ago. It really is a unique game.
