I've been watching Board Game Geek's Sentinels of the Multiverse page, and ever since I first learned about the game back in April, it's been slowly creeping up the list from around 120, and is now currently ranked 99th on Board Game Geek's overall ranking list! On top of that, it's also the 16th highest rated game on the Thematic listing.

it had already been 100 for a brief time some days ago, dropping Settlers out for the first time. But then went back to 103. Now it's 95. Oh my, that's a BIG jump at those stages.
