Caporegime
Mrs recently replayed these on xbox series x (not the remasters) and they all run OK. Mass effect 1 could do with the combat being changed (i think they may have done this) and mako improvements. I would only consider replaying ME2/3 for those reasons.
I don't really think it's worth the £50 on xbox, might as well play the originals that are free on games pass, but that's just me
I have done exactly the same. To think both 2 and 3 are a decade old. I never once thought. I need better graphics to enjoy this. I think this is a major problem with games in general now. Too much emphasis on graphics rather than gameplay.
