I used to think that entertainers were kind of useless, and I still think that's the case in most normal parks, but I've found them to be incredibly useful for crazy challenges where your guests will be unhappy without entertainers.
I‘ve been playing RCT for 25 years now. Within the first years after the release, it was quite uncool to admit that it‘s your favourite game. Little did I know that 25 years later the game would be appreciated by many who weren‘t even born back then. Due to an unexplicable fact, I enjoy videos about RCT as long as they are presented by someone who shares the passion for it. In addition, your ability as speaker is a delight!
If I have a park that needs a huge number of guests with a high rating to win, then long queues are necessary to keep the guests in the park. That’s when I place entertainers in the queues to keep them happy.
I probably should start using patrol zones for handymen. They have a rather annoying tendency to wander off and take a nap instead of cleaning the paths and emptying bins.
If i fast forward and i have a blind spot where puke just keeps on accumulating through the days, vandalls will start wrecking my stuff. I like to have mall cops on patrol so when i do hit that fast forward button, and i do have a blind spot, i minimize damage and spend less time fixing benches.
