DS3 literally starts with a boss that is quite challenging if you're not used to DS already. Just "here is a sword, here is how to swing it, here is a bear of a man with an oozing snake hand - kill him". A lot of players bounced off him.
Fromsoft isn't in the business of making easy games, it's just different variations of challenging. For people that like that it's great. For a lot of people that very understandably is a turn off.
Or GameMaker if you are doing a 2d game, or Unreal if you don't mind the learning curve. Plenty of other options beyond Unity.
