Option 2. It’s the most robust. You’ll never lose it (provided you have the redundancy), you can use it offline, you can transfer it using a USB pen, it’s available in all platforms, including web. I’ve been using this for 8+ years, on my phone, desktop, laptop, company computer, etc. I store it on a personal cloud (and on each machine, of course, by syncing).
Well I’m not a huge gamer, specially since I have a kid, but I was expecting GTA with horses, but I’m enjoying it a lot (I don’t really like GTA) anh I had not played this game, since I never had a console, but it came out for switch and I went for it. I’m not going to try to sell it to you. The no-map immersion is a big factor, I guess, which is new for me!
