In my opinion, its not about "hard" vs "easy", theres more to it, but simply its about "balance" (like I titled the thread). In RCT1/2 you could fail a scenario, does that make it difficult? No but it gives you incentive to try harder, and to get a better score. In RCT1/2 you could achieve a high score, but they removed that aspect from RCT3 and PC, probably to not discourage new players. In RCT1/2 we could purchase land which some might argue is not important, but it gives people choices about how to spend their money, do you buy the pond in the back of your park or wait and save money?
Considering RCT1 is 20 years old, I expected the actual objectives for the scenarios in PC to be more balanced (financially). Many of the scenarios can be completed in under a few months, and the only real challenge to career mode are the few coaster objectives (which do not help new players learn the game) there is no tutorial levels, no progression system, nothing to help new players learn the game. They just throw it all at us at once. I miss the progression I felt when playing RCT1, because each scenario felt like it offered something new, but in PC each scenario is the same large blank open flat square
On top of that, PC is actually a lot more difficult in the sense that it is wayyyyyy more time consuming.... make a mountain in PC takes 10 hours, coaster takes a few hours, but in RCT it took minutes. I actually wish PC was easier/less tedious in many ways (specifically terrain and paths) but I also wish the career scenarios had a better level of progression to them
With challenge mode, the only difficulty is maintain the prices of rides as they age, I mainly wait until I have a few "classic aged" rides and then boom Im rich and it turns into a sandbox mode after 25 years of placing flat rides. Some rides have too much prestige (like slow car rides) while other have not enough (like ferris wheels) its just not balanced
I'm not trying to "push new players away" in fact I think for the reason I mentioned, new players would enjoy a deeper career mode because many casual non-constructive players enjoy playing a simple game with puzzle elements, rather than painting a landscape on a blank easel... thats why games like Parkitect and RCT2 are still popular, but people wish PC had what those older less pretty games have, otherwise this game will remain to appeal for only a certain type of player
You know Super Mario 3 is more challenging than other Mario games, but that doesnt mean its harder to play. Theres a difference between "hard" and "challenge", PC can be hard when the tools are not great, but it is not challenging
