Thinking about picking up FE Warriors after hearing Musou games be mentioned. Never played a Musou game before, but cutting down hundreds of enemies with Marth or any of my other favorite FE characters sounds like a good time.
Musou games can be incredibly cathartic.
The biggest criticism they have is that they get repetitive. But personally, smacking hundreds of mooks into the air and tearing through armies of thousands with style and grace never gets old for me.
