Hehe yeah Daggerfall, it's the game that really got me started on PC gaming (before that I'd only ever really played consoles). Every time a new TES game came out I was hoping for a repeat of Daggerfall's world and randomly generated dungeons but as the graphics improved, it seemed word size decreased
As for the F3 mods, yeah I got most of those expansion type mods already, including the train carriage interiors
I agree with you about the Dunia engine, I played Far Cry 3 for a bit but lost interest in it about mid way through the story for various reasons that I won't bore everyone here with.
While Bethsoft were really great at world creation, they seem to have lost the ability to craft stories.
I suppose some of the signs were already there, their early dungeons were too "cut & paste" and their storylines could be a little same-same after a while and they really, really, really, REALLY needed to hire extra voice actors instead of overusing the three or four (sarcasm) that they have!
Having said that, Skyrim is a fun world space to wander around in but yes, five minute walks to a major town make it seem very small (pretty much the reason I don't bother with the horses, with a backpack mod and a couple of followers I don't need a horse for carrying extra loot and they don't offer any real advantage in speed when town is five minutes walk away).
