So in this thread we argue why games with stats such as HP, MP, EXP and allow you to get levels to get stronger and require you to do some grinding in order to get said levels, and usually have more plot than Sonic 1 or SMW and have a lot of similarities to the first videogames from the late 80s that were cloning D&D the best they could with an 8-bit system are called RPGs?

That's like asking why games where you see in first person and shoot people are called FPSs.
