- Miranda, Garrus and Thane coming back as a squadmate/love interest again.
- The same LI system but let you do more stuff at the end of the game with them. New dialog, some more unique things to do with them in the cabin, etc.
- Planet scanning system (post-patch or faster, and yes, I'm serious) and the upgrade system making a return and have a shitload more upgrades available. Having 100,000 Palladium and 120,000 Platinum lying around gathering space dust was kind of a waste.
- A better squad upgrade system, damn it. Maxing out three of my teammates' abilities and having three permanent squad points left over was annoying. ME1 gave you measly 2% bonuses to abilities from one level to the next with a ton of Squad Points to distribute, while ME2 had higher abilities costing more squad points with less to give out and them being drastically more effective as you leveled them. Personally, I'd like to see ME3 have a happy medium alongside the ability to max your character out. Give the player an even number of squad points for each level up, have each ability cost one point up until level 6/8/whatever other even number, except for the last one which costs two points and upgrades like it does in ME2.
- A higher level cap.
- The same Paragon/Charm, Renegade/Intimidate system, except make it more forgiving.
- The same weapon/thermal clip system but ME1's ammo upgrade system. I hated the fact that I had to use biotics to change my gun's ammo.
- Let me tackle the highest difficulty setting right from the start again.
*dusts off hands* That should do it.
