I'm around 95,000 gold right now, so close. I don't pick up non enchanted weapons usually except the good stuff like ebony and sometimes glass. If it is magical in some way, I'll pick it up. I pick up all potions and gems of course. And all gold. I pick up a lot of robes since they only weigh 1 pound, so if it's worth over 100 gold, I'll pick it up.
Speaking of linear dungeons from above, I don't mind the caves and barrows. They are pretty cool. I should mention there are some above ground places to "clear out" like the one quest in White Run where you rescue the family member from that place up North. Sadly, despite being a fort of some kind, that place is filled with linear hallways which doesn't make sense. The building is rectangular I believe, so why doesn't the inside seem to match the outside? Most interiors of buildings in real life have a rectangular setup so there isn't a lot of wasted space between walls. So why are there long corridors with no rooms on either side? Sometimes it's like corridor, room, corridor, room, corridor, room, etc. But I generally like the dungeon setup visually.
I picked up the dog from outside of Markarth stables, I didn't realize you could have 2 followers. He's not that great, since I can't sneak with him, but he's an alright tank. I have the mage follower, she summons frost astronachs which in theory could be a tank, but I find them too large, and find they block my view of what I'm shooting firebolts at. They just generally annoy me, and I usually kill it after the battle.
And the reason why I haven't seen any dragons in days is because I haven't done the quest: A Blade in the Dark. I'm pretty sure that's why. I did the main quest up until there. I've gone months in game time without seeing a dragon.
