I hadn't thought specifically of a Country Club but I believe the idea has merit. I have worked at two so I can tell you that almost all Country Clubs in the US have these features more or less.
- Ballroom(s) & Meeting Rooms - For event rentals large and small
- Art Expos
- Baby Showers
- Balls
- Black & White
- Masquerades
- New Years Eve
- Charitable Events
- Golden Anniversaries
- Weddings
- Carefully Manicured Landscaping
- Circular Driveway
- Commercial Kitchen - For Food at the Events, and to service the restaurant
- The Course - You could put in a nine hole
- Driving Range
- Gym
- Locker Rooms
- Pro Shop - "I bet if you buy this hat it will come with a Free Bowl of Soup…but it looks good on you"
- Putting Green
- Swimming Pool
- Tennis Court
- Tournaments
- Trophy Rooms
- Water Feature like a manmade lake or pound
- the 19th Hole
Country Clubs Charge - This would be good for those who want more things to spend money on in the Sims
- Greens Fees for Non-Members
- Membership Fees
- Room Rental
- Tennis & Gold Lessons
