That's great that there's some concerted effort being put towards dissolving the term "roguelike". Genre names that live of the backs of other games are terrible. We got rid of Doom-clone, roguelike seems to be on the way out, now we just need to rethink Metroidvania...
We didn't get rid of Doom clones, though. There just stopped being Doom clones. Now they're CoD clones. If no one makes a roguelike game next year, it doesn't mean that the term roguelike is now superfluous.
"Doom clone" was used because it was immediately recognizable what you were talking about. In the same way I know exactly what you're talking about when you say roguelike, and I don't know what the fuck you're talking about when you say "oh this is a Mastery game." Like what? What does that mean, it's hard? Roguelikes aren't defined by being hard, they're defined by having randomly generated levels and permadeath. I don't know what you mean when you say that your new game is an Evergreen game, I'll just assume you mean it's a conifer. I'll know what you mean if you say Doom clone, roguelike, Metroidvania, Diablo clone, Cod clone, et cetera.
Except that all of the "roguelikes" that come out these days bares almost zero resemblance to Rogue.
