Fair, depends on the game. CRPG’s will tend to have it in. I mean for example WotR and Kingmaker you can get a bag of holding if you buy it or put stuff into strength on characters or etc in order to not have to worry about it much but it’s still there, and not spending the money on it or building any characters with strength means you will be limited.

bags of holding.

It's true. The character in my current campaign has two bags of holding and a bag of devouring.
