Eric Barone, the guy who can't stop updating Stardew Valley, says the words "I might eventually make a Stardew Valley 2"

Sequal idea: Same map. Same characters. New added characters. Expanded map area.

But here's the catch. If you want to know where any given character is on a non-event day, just stalk them on that day. If you see a person is at the beach on a Tuesday at 8pm, they will ALWAYS be on the beach at 8pm on non-event Tuesdays.

What if we introduced a needs system? Lets say Marnie needs love. Well she'll go find the mayor. But maybe she needs to shower more than she needs love. Well, now she's going home, showering, THEN she'll go find Lewis.

And each characters needs meters are unique. For example, Pam and Shane could have alcohol needs. But Jazmine might be aged up from age 5 to age 13. She wouldn't have an alcohol need. But she might have a need to be hugged. In which case, she'd go find Penny.

And maybe we introduce visitors. Create like 4,000 sprite models, and have 20 visitors each day visit the town. That way, it's not the same people visiting everyday, but there's always some people visiting.

Maybe make more visitors on Fridays/Saturdays/Sundays, and less visitors Monday and Tuesdays.

And you could tie the games economy to the visitors. The more they spend, the more the local shops can upgrade their shop. But they get incentivized to come spend money based on what quality those shops carry. Which in turn is based on what you sell (or don't sell) them.
