I know that a similar thread was created quite some time ago, I think some where in the Spoiler Forum, but it was only related to Munch's Oddsyee.
Basically, if you want to achieve the highest status in all the games; AO, AE, MO. There are things you can do to go above the Perfect Quarma status. While, the actual games do not acknowledge them, at least you can yourself acknowledge them. Yes, I'm ranting on, and you probably don't understand me. So i'll cut to the chase
Basically, you also have to have achieved Perfect Quarma status, as well as:
Abe's Oddsyee
Abe's Exoddus
- Don't kill any wildlife creatures, including slurgs and fleeches!
Munch's Oddsyee
- Regrowing all spooce so that there is none left ungrown, so as to leave it for later inhabitants to use. This doesn't include the spooce collected in the first few levels with Munch in Vykker's Labs, as there is no way of regrowing them
- All Native Mudokons are alive, not dead inside a Resurrection Totem
Please reply to this thread with more ideas for each game if you can

And reply as well, if you have done some of the things.
I am currently doing all the things listed for Munch's Oddysee. So far, so good!
