I can only agree, I never liked dwarves that much and in many universes like warcraft, lord of the rings and others dwarves are not given a lot of attention because there isn't a lot of interesting things with them. But for some reason, or maybe because people think the majority of people love dwarves and not just a few loud and noisy fans, everybody makes games on dwarves, they are everywhere. And the worst part is that it's always the same thing, the same names, designs, characters, mechanics,... All of them barely different copy of some very boring and overdone theme.
I can't say this will come to an end either, it has been going for years, players are showing by not buying those games who all fail badly btw that they want something new and daring, yet people keep making games on dwarves... As for elves in gaming I doubt anyone would ever dare to make a game centered on elves, i feel it would be too complicated and nobody would ever attempt that, there is a limit to what you can ask people to do.
