- Anything introduced in New Vegas. (hardcoe, worthwhile companions, shandification, etc.)
- Anything introduced in Project Nevada (Sprinting, Grenade Hotkey, Bull rushing, unique weapons, etc.)
- Rifle Bashing/pistol whipping/Bayonettes. Not a replacement for legit melee, but a suitable close-quarters defense for someone who isn't skilled in wielding a one handed blade. Enough to finish off a fleeing enemy or kill a minor enemy (ie a radroach) or knock off guard a charging enemy (IE A feral Ghoul)
- Secondary fire/attachments. Underbarrel grenade launchers and/or flashlights. The Pipboy light is good in a pinch but it shouldn't be the only source.
- Modification system separate from the attachment system IE Stalker COP. Or "Make your own unique"
- NPCs that are able to make use of the above. No more being the only person in the wasteland that can modify weapons.
- Companion command similiar to JIP's C&C mod.
- Ability to salvage, construct, and sell robots like with TalkieToaster's Robco Certified mod.
- More perks, and not just a stupid skill tree system that excludes non-skill based perks and makes it a pain in the ass to introduce new perks.
- Bounty hunting along the lines of Someguy's series.
- Ironsights. FFS Beth it's 2015. No more zoom-in-from-the-side style sighting.
- Companions that not only have backstory but also perks and quests for you to go on as you travel with them.
- Dynamic dungeons. IE if it isn't part of a main quest, you can go to a building and see it inhabited by raiders. You kill them, come back later, and instead of finding respawned raiders, you find critters. Or BOS. or Encalve remnants. Or Supermutants. Or a rival band of raiders. Or other wasters trying to loot anything you left behind. Or a mix of the above duking it out. Meanwhile the original tribe of raiders you killed is sending raiders from somewhere else to take it back.
- The ability to make our own choices based on our own pov rather than being shoehorned into a good/evil paradigm with a phony baloney "evil" opportunity shoehorned in at the end.
