The issue with Europe right now is that their stars don't shoot that much. Back then there was Little Caprice, Alexis Crystal, Sybil A, Stacy Cruz, Nancy A, Jia Lissa, Liya Silver, Amirah Adara, Tiffany Tatum, Misha Cross shooting plenty not just for VMG but for every studio. These girls are mostly gone, and the ones that have emerged aren't very active either. There's Eve Sweet, but then Kelly Collins doesn't shoot anymore. These two had the looks, the performances and the productivity, after them there's a big drop off. Who else is there? Eva Generosi has had 4 scenes this year, Britney Dutch has had 11, 3 of which have been VR so it barely counts. They made Ashby Winter a Vixen Angel a few months ago, which means she barely shoots anymore. Bella Spark had the Bang and Burn showcase last year, has only shot 7 scenes this year none of which have been for VMG. Lily Blossom has had 2 DPs for VMG this year but has only had 13 scenes this year, 4 of which have been VR. There's Dolly Dyson and Catherine Knight (who's technically South American) but they mostly make content rather than studio scenes.
So yeah, these are currently the biggest names but they don't shoot that much. There are these two new girls as well, Sumiko Smile and Kity Wild, they look promising but haven't shot for VMG yet.
