Sinotek, it has a great story, it has plenty of dialogue, it is a long game (well worth the money spent), in that aspect it matches TLJ. But the stories would be a stretch to try and compare and I think you'll be changing your opinion as you get further along.

I'm sure you're right.

All this discussion made me wanna keep playing Culpa. Too bad I won't be able to until tomorrow.

I really miss story lines like TLJ. So far, I only found 1 game that had an awesome story line (close to TLJ). It was Indigo Prophecy. Man that was a great game...
P.S: I just found a review for Culpa, but I don't know if it's allowed to show the link for it here, so I won't. But in this review they talk about TLJ as well. Check it out:
Now, you may have wondered while reading the first paragraph of this review why I mentioned The Longest Journey. That is because I was among the people expecting a wonderful adventure game saga but sadly saw it deteriorate to a casual console-oriented hybrid. Culpa Innata rekindled this expectation, and with the ending of the game leaving questions unanswered in an X-Files kinda way and doors open to sequel(s), I am dreaming of more and can barely hold myself from p**ing in my pants with anticipation. This is the saga we’ve been waiting for. Thank you Momentum.
The game got +A from them. Pretty impressive. Now I really want to finish it!
