Oh, Crimson Desert's main quest is a lot more engaging than that of the average Bethesda game. I couldn't name you a single thing that happened in Fallout 4's or Skyrim's. And the only thing I remember about that of Fallout 3 is that the climax involved a giant robot and at the end you had to sacrifice yourself for no reason.That only applies to linear games, not games where you can just set forth from chapter 1 and not do any main quests and just explore and get lost in the world for tens of hours. Can you imagine if Skyrim was handled this way? Do you remember its reviews and how each person had their own little adventure based on which direction they set forth towards, all of them ignoring the main quest? Same thing here.
Like I had a good 10 hours before even getting the grappling hook and flight just running around doing things.
I can see if you are a psycho and just ignore 99% of the stuff in front of you and just do the 3 main quests back to back how that could be boring but the same could be said regarding skyrim too and in neither case it would be a reasonable criticism.
I think the issue here is that some of the people judging the game just didn't care to actually enjoy it so they phoned it in, meanwhile most people back in the day were super excited about skyrim and put in the necessary effort towards enjoying it.
And let's not even bring up Starfield. I didn't even finish it, and there's a reason for that. And it's not because it's particularly long.
