I used to love sunset Valley, and I still know it best. But I've found in the last year that I absolutely love Riverview. Especially with Ambitions and Late Night additions. The empty lots and the bridges, the little suburban area for families, complete with a personal park geared towards the little guys, it's all fantastic. I especially love the Watering Hole and Warehouse. I've recently turned the Watering Hole into a dive bar, and the Warehouse into a Dance Club, at least I think that's what it's called. The only problem I find is that all of the eligible bachelors are rich, so I tend to make couples for Riverview. Or just not have Sims get married during the first generation. I also love the garden and the library, the library is lots of fun for books, especially because it's located so close to workplaces! And the garden is great for beginner gardeners to gain some valuable harvestables and skill points!
