I think Bayonetta would be more engaging while Hyrule Warriors would be more mindless and fatiguing.

Really depends on if you want a game to take it easy with or something more focused.

There's probably more content in Hyrule Warriors though truth be told, more "content" in a Musou game largely means replaying the same maps over and over with different characters and conditions. That said, it's still pretty fun.

I voted for Bayonetta though because the campaigns will last you most of the day and replaying them on higher difficulties is, in my opinion, infinitely more fun than anything Hyrule Warriors is gonna throw at you.

I feel like those Omega Force Warriors/musou style games are basically something that people play while listening to podcasts and stuff and they're not particularly engaged by the game, it's just sort of a shut your brain off and autopilot while paying more attention to something else. That can be a good way to relax etc, but if you're not juggling any other games, it might get old kinda fast.

On the other hand, I think the Bayonetta series is the pinnacle of its genre and I'm surprised that mine was the only vote for it at the time I voted. This has since been remedied!

Hope your hospital stay goes ok, duder!

Bayonetta!
