Let me start with mine: Control. It hits almost all the aspects of a great game, but the navigation is frigging terrible and made my time with it an slog.
The game has a mission structure, and gives you just general directions of where to go in the mission briefing. However, the combination of vague directions, a very puzzling building layout and a insufficient 3D map made finding out where I was supposed to go a much bigger challenge than all the other game mechanics. I found myself looking at youtube to find out where I was supposed too go until I realized I wasn’t having fun with the game, so I stopped.
