People are not going to build games for nostalgic reasons just to make a quick buck or to please just one small niche community.
Your community is even smaller than the real-time RPG community. Original Sin II sales don't even hold a candle to the Baldur's Gate games. Even new entries like Pillars of Eternity outsold Original Sin.
First, realise just how small you are before you talk like this towards others. It's you who is the tiny minority niche, trying to hijack a larger franchise and destroying it.
