Took way to long to reply to you. Sorry for that!
Character customization (design) is one of Mot's biggest skills which makes his characters unique compare to standard DAZ 3D models used in other games.
It's hard to find good and royalty free tracks that go hand in hand with the scenes.
Nika is fan favorite no. 1. People went nuts about my custom render of John fucking her in the same was people went nuts about Gaz giving Bacon a lapdance.
Personally, same as you, I would love to see a threesome scene with MC, Nika and John or even a scene with Juli, MC, Nika and John.
But I'm not the one who makes the scenes, so I or we only can dream about it.
I can relate to your points but on the other hand it was necessary for the build up.
Right now MC is stranded in the past and who knows if he ever will return to his present timeline or not.
Updating more often would mean smaller updates or less quality renders. For latter I'm not sure if Mot is willing to do that. He is after all an artist with his own standards.
Let's be honest: Monthly updates will burnout any artist quickly. Look at Braindrop - he used to update monthly and now he hasn't released an update in a few months. Same goes for many other games. Look how many games got the "on hold" tag which received updates frequently.
People really underestimate how time consuming creating renders and animations are. When I get up at 6 in the morning I have to tell Mot to go to sleep because he still is doing final posing before he sends everything into batch-rendering.
More money won't speed up developing time because it is extreme hard to find a second artist who is able to match another artist skill set. Means, you can buy a new render station but still only have a single person doing posing and everything else. (But I don't have to tell you this since you have an artistic background.).
However, I'm sure that RL 8 is going to be lit... maybe we can add some Bacon-Juli action to it
(calm your tits you angry mob it's a joke!)
Btw: Milf focused games aren't well supported compare to loli games. If you want to earn some easy bucks then you should create a harem-loli game with medicore renders and people will gladly support your project.
