Because when it does update after 6-8 months of waiting, the content is actually really good. The graphics are fantastic, the animations are fantastic, the writing is great, the dirty talk is great, the fetish content is great, the characters are actually unique and memorable, the script is clean, no typos or bad grammar and the game actually allows me to be evil. How many games on F95 check all these boxes? Not a lot.
Yeah the very long time between updates is frustrating but there are thousands of games on F95, most of them not actually worth playing. If anything western porn games have a quality, not a quantity problem. So I would rather wait 8 months between updates than to play yet another cheaply made game, with a barely readable script, no animations, no sounds, bad renders, etc.
