Some pieces didn't fit well. Rope pieces required to be tied.
Have a very large tray for all the pieces because the bags are not matched to the 'play well' instructions.
My 7 year old still put it together no issues, just took a few days due to the piece count.
If you want to save serious money and not support scalpers/'bricks as bucks' investors, then Joy here was a pretty decent experience for the cost.
