Depends -- do you want to play it or just look at it. If you play it, it will get dimples, but they will flatten out after enough plays. Otherwise, clean and wax regularly, and use premium balls. Check the balls each time you clean and if they look scratched or have any other physical marks, replace them (or replace them once or twice a year, depending on how frequently you play).
Just think that if you place 3 games a day on average, you are putting about 1100 a year. I know that even for my most frequently played games in my collection, they don't see that kind of play.
