I think some people just really like the lifetime dev stuff. The kind where devs keep saying how much they will just keep putting into the game. NLT actually finishes their products, which might be both good and bad. They can show they are able to deliver a finished product, but, people might just want more content stuffed into what they already have.
NLT Media's output is outstanding graphically but the characterisation, dialogue, plotting and storyline is often shit these days. Plus NLT's MCs are always short, weak, weedy and often nasty pieces of work verging sometimes on abusive if not rapey behaviour: The "serum" device used to explain why all of the women are, or quickly become, nymphomaniacs, verges too near to a "date rape" scenario as well for my liking. To be honest NLT games are now little more than visual stimulation to help masturbators jerk off rather than sophisticated sexy entertainments satisfying all types of players, from lonely brain-dead fappers to sophisticated college graduates.
I am a patron of NLT Media currently but personally, perhaps because I'm lucky enough to have a lovely long-term girlfriend, want more from an adult game than a series of beautifully crafted, often animated, sex scenes bereft of dialogue and drama. Many of NLT's efforts to portray sexual variations, particularly when two or more female characters are involved, are most times utterly ridiculous, ludicrous, laughable and boring for a sexually experienced person, able to recognise how impossibly daft they are, which of course is a big fail as far as a games in this genre are concerned.
That said if you're an isolated virgin, frustrated adult, or just sexually naive with a need to fap NLT games should serve your needs. A word to the wise, young and innocent: The sex in NLT games is fantastical and nothing like sex in real life. For example: Almost all girls hate and are revolted by anal sex. If you're curious why that should be the case after seeing all those NLT babes enjoying the hell out of being drilled that way in the games, try sticking something about the same size and shape as your erect cock up your own ass and you will have the answer!
