Let me start, then. Since I haven't finished the game (and I have this game for long time
I added:
-A house in Balmora (no new NPC nor weapons) for nice place to sleep and keep all my staffs.
-A mod to change my potion bottle designs (easier to identify and organize my medicine cabinet)
-A mod to give Creepy more money (I can't waste my precioius time for barter, you know. I only did that for Creepy, though. No new merchants and no one else has more money than original. I swear!)
-A Travel by Sea mod (a few more new travel routes from Seyda Neen.)
-A house in Dagon Fel
-Real Signpost for better signs
That's about it. Now, it's your turn!
