I want sims to start being charged Admission for things.

That would make for a neat lot trait, or even a toggle so you wouldn't need to "waste" a trait on it. I remember having a mod a while back that did this, as well as one that allowed sims to buy and own any lot type, I'd love to see some type of lot management like this in a future pack.

There is a mod that does this bit yeah I think an in game lot trait to add a fee would be good

I don't want it tied to a lot trait, I downloaded that but it's annoying to get charged to hang outside the lot. I had a club outside the spice festival lot and Sims were charged for the club when visiting the festival. Oops!

I want it tied to objects. A barrier rope gate, a door, a turnstile, etc. I also want different options that make sense for different lot types. For example, a carnival could have a turnstile, but other lots could even have a combo of a barrier rope with staff who takes your ticket, or a bouncer. More room specific, if we want, rather than whole lot.

i fully disagree with this idea not someting i went in the game since i play the sims4 to escape realty sometime not to recreate it in game since i also keep aging fully turn off.

That would be nice. I never really thought about it, but it is weird for sims to just waltz up into museums and clubs and not be charged a cent.

They should bring back the Barrier To Entry System! https://na.lvlt.sims3store.cdn.ea.com/u/f/sims/sims3/sims3store/objects/TurnstileDoorCollection/Thumbnail_300x300.png
That would allow for more customization, like for example having another area you can enter by paying or having two nightclubs on one lot.

Yes! Barrier system would be really cool, would also really like it if libraries and museums weren't open 24/7 I'm not sure where libraries and museums are open 24/7 I personally just want the game to be a bit more difficult. even rags to riches challenges aren't that difficult.

This would be cool, especially if, like you say, if was something the player could choose and design for their lots. The drop down sounds nice--I've always wished there were more options like the for restaurants for other lot types. You could just add a "fee" and you could set at various rates, and maybe even dress code option as well, for each public venue.

Sounds like the Bouncer door to me. Which we already have.

Yes make the simoleons more meaningful like charging gym membership for 3000 simoleons a week cancel anytime.
