Well, I know the question was to Zorlun and not me, but...Do you still get the time to play them?
Played AWAM once or twice, dropped it, as it sounded to me like milking (though I had not started sponsoring, so, cannot complain) - I like a good story, even in porn games and porn (don't laugh, I still remember an "alice in wonderland", definitively a porn, but with a story, and an actress that was very cute, not "inflated", and who could actually even sing and act, though it was a very old one, 70s), but the story did not impress me especially, and AFAIK it is a slooooooow progress and development (especially if you compare it with the almost monthly release from Zorlun ;-)).
Never played project Sage, but I did play, effectively sponsored, GGGB - it has been quite a long time I have not played it anymore, but I did play it a number of times, some even after I started playing and doing the patch for Myriam, I really liked that game, all the possibilties, even the drawing style.
As Zorlun says, I also would have liked to see some extra thing there, but not so much to feel it is not a good game to enjoy.
Though I would say it is anyway very different from Myriam - if you are liking Myriam, do not see them as alternatives, but rather as complementary.
