I fooled around with the programm as a child, but never made a proper game of any sorts. I didn't start Renryuu that long ago obviously, Renryuu came way later. :D
Renryuu wasn't a hentai game at first. The first idea everything got build up upon was to make the worldmap on which you can govern a country. I had no story or party members planned at the start. ^^
I worked on the game for a long time before I got to the point of thinking "hey, let's upload the game somewhere so that people can play it and give me feedback". The feedback and seeing that people enjoy it got my motivation rolling and with the increasing support slowly got me more and more serious about it.
I think MV was the best PRG Maker so far for me.
I think there are enough "text-only" games if you'd like that. A game like Renryuu works a lot with visuals and effects, not showing anything during the sex scenes would feel like a let down to me.
$ was the default currency set in itch I guess as I didn't change it. ^^ Since I pay my artists in $ anyway, it might not be a problem to keep it that way instead of changing it back and forth.
The CGs are based on my thoughts and descriptions for the scene, but it's easier to make the text with the CG so that all details I describe during the event fit to the image.
If we're talking about eroges, the japanese company Eushully has a very special place in my heart. They have great hentai games that combine a CG style that I like a lot together with proper gameplay. Since most japanese eroges are just visual novels the varying gameplay systems of Eushully games are something rather rare. And because I can't enjoy pure visual novels in japanese due to my lack of speaking the language, I prefer eroges with gameplay to take a break from the "work" of translating the dialogs. :D
