So many bugs still even when the game came out years ago, its super finicky and will just frustrate you. community is also terrible and they will just claim that its not the game and that its you. Would definitely not recommend this game. Pathfinding is broken and unless you want to have to hold the games hand and manage every single little thing down to how employees get to job sites I would not recommend

Welcome to Parking lot Simulator.....

But in all seriousness... I have a good time with this game.

Once you get the hang of some of the basics it is just a matter of tweaking it.

Like a lot of comments, the game could be so much more than what it is now.
They could of worked a bit further in making the NPC follow the path you want them to take. For example have doors become only one way doors. Blocking non staff from going through but staff can. Or even making sure some items can only be passed on way like the gate to let people through to the plane. Why do NPC goes through and ignore the one way system is for me making me quit the game.

What is the point of making a beautiful and cool airport if its for your NPC completly ignoring it all.

The number of times i have NPC going all the way to the arival area just to sit down at a bench. That has one closest to their gate. What is the point of walking so far for a sit? Broken NPC and i dont want to work around so many weird handling of the system. I quit. Its sad. But i am done.

If you think of getting the game, be ready to be triggered by the path finding system ignoring your airport layout. It will ruin your fun.
