As others have mentioned, as I grow older I play less games. However, I recently purchased an adventure games bundle [0] for the iPad and I've been playing for a couple of hours every night for the past few weeks. There's no IAP or ads in those games, just good old one time payment for content thing. I have nothing against playing mobile games, unless it's the cancerous ads plus ridiculous IAP business model.
