The condescension towards people who will play this game for the first on Switch is amazingly hilarious.
There's quite many similarities from the methodical movement to the restricted item usage and management. Both series reward careful planning and punish the player for any mistakes.
Outside of a few general similarities, I don't see it, positioning is way more important in MH than DS being the latest movement being less restrective specially in low weights.
DS explore elements, totally different gear system and progression makes for more than different experience. I don't think planning is that important in DS, for starters or item management for that matter, compared to MH.
Except of the more weighty deliberate combat, for me both games are really different in a way that I'm the biggest DS fan but MH never manages to fully grab me.
