Those are perfectly valid questions, not weird at all. What would have been weird is if you'd asked me if I like to rub melted butter all over myself before I start working, which I don't, but still, would have been weird to ask...
Anyway! I can see you're not very familiar with the way RPGMaker works, and I might not be the best person to ask about programming or language, because I don't do any programming at all. That's the thing with RPGMaker, everything's pre-programmed, and you have to select from a menu what you want (add condition, character move left, right, etc...), like this:

That makes it very easy to grasp, and I didn't really need help from other devs. I watched a few videos here and there, then started with HC1 right away and learned the rest while developing. I started it because I really liked another game by a Japanese dev, but he disappeared suddenly one day, so I decided to pick up the slack and do a similar game, telling myself "how hard can it be". It was hard, but fun as well, so I kept going.
I do have plenty of artists helping me with the game, from one at the beginning to up to 4 at a time now, but I'm also making plenty use of the free assets that come with buying the game + there's a good community providing free assets as well.
I didn't do much promotion besides here on F95. I've noticed that the amount of work/yield ratio is the best on here, the other websites aren't really worth the hassle. I did a few cross-promotions here and there, but it didn't yield anything, but that's probably due to how tightly-knit the NTR community is, so most games that deal with this fetish are already known by most within it.
That's about all I can tell you. Do I plan to incorporate new technologies? Maybe. Depends on the technology. There's already a more recent version of RPGMaker that's been out there for years, but I've held off using it because it doesn't quite have the same level of customization and community-made plugins the current version I'm using has.
There, hope it helped a little bit : )
