Is Octopath worth buying the Switch for?
Kind of a vague question I realize, but the game intrigues me, the system itself...not so much.
No, I wouldn't buy the Switch just for one specific JRPG, but I also wouldn't buy any gaming system just for one exclusive. I really enjoy Octopath, but I wouldn't drop ~$300 to find out if I like it or not and if not, have a system you're not interested in. The Switch has tons of great titles out right now, so I would think if you're into gaming, you'd find more titles to play other than Octopath.
If you have the chance to borrow a friends Switch for a couple hours, download the demo. It gives you up to 3 hours to pay the full game with any character you want. If you're still on the fence, you could delete that file and start with a new traveler too.
If you have any other questions let me know. I'm about 38 hours in to the game and am about to finish up everyone's chapter 2.
