Agree with a lot of what has been said, to recap and add: 1. UI mods, specifically Darn and iHud (which Gopher has confirmed he will be working on once the sufficient tools are ready) 2. Bullet Time - IMO an essential alternative to VATS, I often don't feel like using VATS 3. Ammo crafting/ammo types: I agree with whomever said he doesn't understand why this wasn't already part of the base game - having the ammo types of say, something like CASE with a second option at the weapons workbench to craft new ammo would be great 4. Improved ballistics and physics mods 5. Retextures 6. More base weapons - maybe I'm a bit of an armament hoarder but I like having lots of variety, I'd also like having certain weapons from previous games again, e.g. AMR, Pulse Rifle, old school Gauss Rifle, LMG, more shotguns 7. Better weapon sounds - a lot of the times I feel the base sounds lack a certain oomph 8. Enhanced Camera Mod - because it's nice having legs and actually seeing your own body when you look down 9. Quest Mods - things along the line of New Vegas Bounties, stuff that makes you come back to the game 10. More Perks - something that is never a bad idea, I hope this new system as opposed to the old list + image won't make it too hard to implement them.
