I am making my way through Yakuza series right now and while playing 5 I realized that I am not that invested into the game’s combat, so I turned it to easy and that just streamlined the combat so much for me. I would recommend to maybe try Yakuza 0 on normal at first and then just switch it to easy if you feel like the gameplay might be dragging on.
The OP does not talk about speedrun and challenges. The one guy in the comments just changed the discussion topic. And even if so, Speedrunning and exploiting glitches has nothing to do with playing the game as intended or the experience of the game. And yes off course speedrunning ruin the experience of the game, as it is not playing the game as intended (unless it is specifically a speedrun game, but that is an exception and not our topic). That is a whole another topic and has nothing to do with our discussion and has nothing to do with the initial OP topic.
The OP asks what games to play on easy and which games he recommends, and I told him what I recommend or when I do not recommend playing them. It doesn’t make sense to you, because you are conflicting different issues with the topic. Speedrun is not our discussion (that guy just started talking about it).
You do seem to be simplifying what a game is, though. Boiling it down to what is “intended”. If easy difficulty was created and put into the game by the developer, is it not intended?
