Maybe it could be helpful in which century the park is going?
The 80's? Or more the laterly 50's?
Old-Shops:
-> don't use, i repeat "DON'T" use the ingame standart ones!
Shops like Restaurants, Giftshops and others are be build with CSO's to become an way more realistic touch.
If the shops should be peepable, than you can use the "invisible" ones from Belgabor-Set:
"belgabor-invisibledoodadsv1"
Old-Rides:
Well, old century -> Wooden-Coasters are on high priority.
I know there were some steel ones in the older years too, but most old and meanwhile closed parks have alot of Wooden ones. If you want also steel ones, than the Looping-Coaster (representing Schwarzkopf) and/or an small Kiddi-Coaster Type were an option
Old fashioned things:
I think you must work with a lot of different cso sets, because there is no special set out there that have the things that you are searching for.
And we have the same question, in which century should the stuff be?
I mean for an example an "Q-Line TV" in old-Style is not realistic if your park is build in an century where the TV was not researched, right?
So, sry that i haven'n any links for you.
