Not years, I think they've mentioned it but mostly up until earlier this year they were just on a hiatus not releasing anything for 14 months. Now they're in panic mode they've talked about finally bringing in combat drill, bringing back the VR functionality they removed and upgrading to UE5 as potential next steps.Didn't the dev claim they've been porting the game to UE5 for years already? These mfs got dementia.
Presuming they've steered this toward a UE5 upgrade as it's the least possible work that can be used to drag things out for another 6 months or so now that their subscriber count is back up. VR mode would probably be impractical to integrate with Harem and combat drill would require significant dev resource which isn't Helius' strong point.
They'll probably keep dragging it out until their subscriber count drops again then rinse and repeat. Maybe if things get really dire they'll say they're reversing course on Harem mode and have another rebuild.
