I must agree with K0ng...
(BTW: Don't hold back K0ng...
Tell me what you really think.)
Peeps add a whole other demention to the game. You get to find out whats popular, and what's not, (so you can replace it with something better.) You can see the guest numbers peak and valley on a chart over time. Overall opinion of the park & attractions. Plus the ambiance of people talking, screaming, and walking. It adds so much. Which is why I like peep-friendly.
But then, I also see how others have taken this game, as a sort of working model for amusement & theme parks. Things were hacked and thus, unrideable. A lot of other things that are created this way, are never intended to allow peeps on them in the first place. So why bother with them? This cuts out a lot of extra work, (shops & stalls, trash bins, benches, handymen, security, restrooms. All that is cut out of the picture and it makes for faster park building. Also, opens up a few slots that way.
I just like the peep friendly parks over the peep-less. But I don't judge a park if it allows peeps or not. If it doesn't allow peeps, I take that for a sure sign of hacks and otherwise "creative-re enforcements". But I do like to see the stats of rides. It helps make a better decision, NOT based on looks alone.
I'm more into making rideable and safe tracks. If Asp breaks down with four trains on the circuit, it can slow, stop and hold all four trains at the break run. The trains also make it back to the station, if their stopped at block entrances on the circuit. I determine the most trains it can run, add that many trains and create a shuffle track between the loading station and the unloading station. You turn it on, add a mechanic, and forget it. So there's a lot of different things that attract people with different ideas to RCT.
