hey guys i apologise for my noob 360 questions but at the minute i have a few 360 games that i use on my series x, when I get a 360 im wanting non backwards compatible games for achievements, so I was just wanting to know, if I played a game like for example kameo on my series x and got all achievements, would I need to get all of the achievements on my 360 as well?
