Yeah, I was 30 hours in and had already summoned Steelbeard and the Skull Scepter would not summon him anymore, so after I finished all the quests I could not get past having all of the artifacts. I was pretty mad, but I started a second game, and I must say the game has more replay value than I thought it would.
I would've agreed with you only two hours ago. Now I'm really pissed off at the game as I'm completely stuck and not able to continue the game due to a bug.
Spoilers: I finished all my quests. but because I had killed Garcia and sided with the inquisition, I can't access the Isle of the Dead. It just doesn't show up as an option on my map.
I wasn't having a great time until that.
Oh a separate note, I really enjoyed playing this game. Subpar graphics, an indescribable amount of glitches, and pretty jankty character movements aside... I did enjoy the game. I have waited years for a legit pirate RPG to come out, but I must say I am pretty disappointed with the developers on this one. I personally would lose myself if Bethesda ever decided to develop a pirate RPG!
