User blog comment:H-Man Havoc/ME3 Recommendations (Everything except plot improvements)/@comment-730941-20100719070009

These are all great ideas.

I'd welcome greater customisation in general - more facial options, customised armour pieces, more sense of 'unique' and powerful weapons and armour akin to KoToR's lightsabres. I'd like upgrades to be non-linear (as someone suggested) and modular, so that one could gradually upgrade their sniper rifle (for example) over time and among several branching paths so that it was a unique weapon suited to the player's particular tactics.

Perhaps some more inspired level design - I got a bit sick of repetitive corridors and boxes for cover in ME2. Zero-G or close-quarters combat would fit the universe nicely.

And since you're asking, more romance options as well.
