You need dozens of hours just to get the grasp of mechanics and UI, less alone to figure out whether you even like the game
The problem with this thinking is that you split the game in 2 parts: first a tedious learning process of dozens of hours, and then an enjoyable experience once you know how to play, and imply that you need to get over the first part before being able (or allowed) to rate the game. But the learning part is the game, even more so if you need to invest dozens of hours.
Many players will simply enjoy the grind of Mount and Blade, because they don’t care about the endgame. Many players (maybe the same) will uninstall Dwarf Fortress after half an hour, because they will estimate that the learning curve isn’t worth their time, even if it was the greatest game ever.
