If you liked Planet Coaster 1 you will like this game.
I personally think it is super fun. There are things that I love and things I hate. Overall though, I have never reviewed anything and I wanted to for this because it is a complete game. I don't understand why there are so many negative reviews. Some minor bugs yes, NOTHING is game breaking. Just slightly annoying.

Things I hate:
How I have to click "x" on every freaking menu.
The stupid custom button.
The building seems downgraded. My coaster has no hit boxes???
The new delete button rather than right click.
The new menu for staff is complete trash. Confusing for no reason. Bro IDC if Janitor 1 works 9-10 breaks and then 11- 5. I just wanna build cool coaster.

Things I love:
Building Flumes is SOOO fun.
The carer mode is significantly improved and is very fun.
Finally they have custom themes for flat rides. So no more planting 1,000 trees to get that good rating on teacups.
The game runs like butter. So smooth.
The quality is just overall higher. Other than the bugs, things just seem to work better.
Building Pools is really fun and they did a good job with it.
Scenery is easier to place, paths are easier to place. Its faster + easier to place what you want where you want it.

Things I find Mid:
The new path system. Its OK. I don't understand all the hype for it.
Day cycle seems fine. I need more time with it.

Overall its so worth the buy imo. You will have fun. Ignore the dramatic reviews. The game runs great, its very playable, and has minor issues. The Ui isn't near as bad as people make it seem. For the most part it is the same as PC1 But there are some annoying aspects to it.

Peace
