Luxury problem. Which game to play?

Within a few days GT7 comes out and I can’t decide whether I should buy it or not.

I play ACC most of the time and absolutely love it. Next to that I also have Automobilista2 which I really enjoy and to a lesser extent AC.

I’m afraid that if I buy GT7 that there won’t be enough incentives to play the sims that I love to play.

My question for you is: How do you choose which sim to play at any given time? Do you focus on one sim and play the others to a lesser extent or do you have a rule in your head that decides which game for which kind of mood?
