I got steam like 5 months ago and have now built up a lot of games that i have 100%ed a couple games but pn the main library screen, when you set the "sort by" to "achievements complete" it puts the 100% at the top. The thing is i don't know how it orders the games which are 100%ed. Like i have tried checking every possible thing i can think of and I don't think the games are ordered by amount of achievements in them or by playtime. I need to know it's really bugging me :(
