I don't think you people will be able to handle this. The old Ultimas were HARD.
- No automaps.
- No quest tracking.
- You have to keep track of everything on paper (NPC text that sounds important) mark, organized by town, mark off when done.
- You have to do some fairly sophisticated putting two and two together to figure some things out - sometimes it will tell you 'hey, you should go over here and talk to this guy and ask him about this', but sometimes you need to figure that out yourself, and if you don't, you are stuck, especially for the endgame stuff where it's all multiple hints.
- All the mechanisms predate the conventions you're used to, so they will feel wrong.
Nothing you've played will prepare you for this unless you grew up in the Bard's Tale / DQ1 age. Heck, I beat this game when it came out - it took months, and now even I find it too primitive to really play.
