I have always enjoyed strategy games the most and a few years back I briefly used a service like GeforceNow. Since input lag is not super important for those games, I enjoyed using it and didn't have a lot of problems. If I would start some casual gaming now, I would probably use such a service since I would definitely not get an extra computer and like the simplicity and availability (I just need a laptop and a stable internet connection). I use an old macbook with a crappy inbuilt graphic card, I can't play anything.
