Planet Coaster would be a good base to start from. I know P.C. has been updated but is there a proper economic challenge now as I remember that was a bit weak on launch? I prefer to just plonk down the pre-built stuff myself.
There really isn't an economic challenge. I give it a go every update and have been there since day 1 Alpha but nothing on that side has improved. Weak is understating it in my opinion to the point that the older series was better management, Theme hospital had more interest in staff hiring and training ten fold and that is what worries me about them doing this.
They simplify their games to the masses and it takes away everything a tycoon styled game should be
