I don't know if I'm missing something or if you are really just supposed to grind from the very start, but it stagnated really quickly for me when I was only unlocking new things that cost >$1 million to build when I never had over $250k in the bank (and that was from tickets!) I never even got to build a single roller coaster. It's got potential and I feel like I gave it a good try, but it's just a half-Gig buggy game with bad pacing. ¯\_(ツ)_/¯
