You'll have to commit to Pokémon Sun or Moon if you're going to see either game through: This is a game best enjoyed while curled up in bed or filling 45 minutes of a train commute -- not so much while waiting in line to order lunch. Unlike the immediate gratification of Go, it's a slow burn of a campaign that gradually rewards you over time, and the early hours are pretty quiet. It's also not available for smartphones, meaning you'll need to carry around another device to play.
If you dug Pokémon Go's classic flashback formula but craved something a little more complex and engrossing -- and playable on your couch -- you're in luck. From what I've played so far, Pokémon Sun and Moon are as strong as the series has ever been, layering on fresh content and tweaks without muddling or exhausting the proven formula. On the other hand, if you lack the motivation to stick with a game for 40 or 50 hours, or just want something to amuse you when you're out and about, Pokémon Go's bite-sized thrills remain a better fit.
