RPGs and RTS games in general take a lot to create and balance. More so than the general indie dev could afford, unless of course they hit home run on Kickstarter, but that bubble burst a while back.
I blame this lack of more varied releases on market stagnation in terms of creativity and innovation. In recent years customers have been increasingly used their phones more and computers less for entertainment. This ultimately makes casual platformers that don't require a lot of attention to details or story a lot more intriguing. Since a person's attention span has gone lower and lower with each passing year as we are bombarded with a constantly increasing influx of information, less people dedicate resources such as time and money towards extensive video games.
Unless, of course, you're a big brand company and deliver products with quality on par of CDPR or have big marketing budget like Bethesda, you will be overlooked a lot.
So what could an entry level studio create in order to set a precedent in the market? Most of the time they will go for something really standard that will at least allow them to gather some experience.
