The game engine should not be a factor in my opinion, but sometimes I have some feelings. In the end ultimately the game itself and how fun it is is the most important factor.

• Unreal Engine 5: This engine has such a poor reception for me, that whenever I see it I dislike the game before even having a chance to play. Its not fair I know, but its also not my fault that I think like that. Often games with this engine have stutter issues, require lot of resources and for whatever reason, most AAA games launching with this engine are in a bad state. In the end I will buy a game if its good, obviously, but the engine has a little deciding factor to look deeper or not… even if its just a little factor.
• Unity: I personally don’t like Unity anymore for the bullshit they did. But if I am honest, if the game is good then I do not care if its in Unity.
• Godot: I really want to like games made with this Open Source engine. But if I am honest again, I would not buy a bad game even if its made with this engine.
• RPG Maker: I am a fan of oldschool RPG Maker, so I don’t mind that. But whenever I see made with RPG Maker (or suspect it), the value of the game goes dramatically down for me.
• any custom engine: I highly respect good custom engines, made specifically for the game or company. They often feel and look different, so its actually a factor. Or at least it will make me curious and look deeper into the game.
