Dragon Quest. Because they know what people want and they will never touch the winning formula, because if they do, people will riot.
I can say that because I recently played DQ1-6 and currently DQ8 again. It's basically the same great game over and over with a few nice tweaks to surprise the players without overwhelming them or breaking the formula.
If you demand respect or gratitude for your volunteer work, you're doing volunteering wrong.
