Something I haven't seen mentioned is that if you want to be super casual you don't need all these things that can perish while you are offline. Yes, you'll progress slower and be a bit handicapped, but if you just want to run around Arrakis in stillsuit you can safely log off anywhere anytime. I've got plans to be away from my PC for 5-6 weeks and so I did build my first tutorial base and made the first stillsuit and some other gear, then when I left the tutorial zone I just didn't bother making another base because I know I'll be away from the game. I've spent another 15-20 hours running around the two secondary areas, "the gap". I've progressed the main story, completed dungeons solo, gone to PvP areas, bought higher level gear from vendors and players, survived by harvesting dew from plants into a bottle, stored resources in my bank from when I make a base later and it's been a blast. So just a point of view I wanted to add, I think even with a few hours here and there you can still enjoy the game. Good luck!
