Ok, I have a whole list of mods I used on my last play through.
This is for ME3, because I had to wipe it and reinstall in a certain order. I found all of these in nexus mods:
LE3 Community Patch Expanded galaxy map EGM Armors Druu's Modding Citadel extension (ending?) mod/CEM (install before AHEM) Appearance mod menu (I went a little crazy with this one) Audemus Happy Ending Mod (AHEM) A Lot of Videos Immersive emails Take Earth Back Remove Shared Cool down Miranda Mod Unlimited Sprint Unrestricted Weapons Upgrade Silent Traynor Spectre Expansion Usable Hot tub More Gay Romances Tali Overhaul Unique Aquarians Prayer Book Emily Returns Custom Asari Adept Armor Admiral Xen Restored Journal Enhanced Laugh track (plays when you die) Project Variety Thomas the Tank Reaper (yep.) N8 Weapons Remix
I also downloaded extra outfits, hair packs, and custom character designs.
It has been fun.
