Obduction is a really good adventure game. You should play it.
I finished the game a week ago and I've had a heck of a time thinking of anything to say. To be sure, my Myst review was written in 2002 and my Myst 5 review in 2010, so the sensible course is just to wait five or ten years and see where Cyan's gotten to. An Obduction review will make an excellent retrospective.
But I do want you to buy the game. (To help make sure Cyan makes it another five or ten years.) So, yeah, it's a really good game and you should play it.
Some of the Obduction posts I thought about writing, but didn't:
Comparing Obduction to Myst. Everybody else has done that. Summary: it's Myst except larger, and also Cyan has gotten better at story and puzzle design. End of blog post.
Comparing Obduction to Riven. Yeah, Riven is also Myst except larger and with better story and puzzle design. So Obduction is pretty much a new game as good as Riven. End of blog post.
Comparing Obduction to The Witness. Problem is, my whole Witness post was just comparing The Witness to Myst. Summary: The Witness really has no interest in being Myst. It's doing something else. Obduction is doing the same thing as Myst only Cyan has gotten better at it. End of blog post.
Talking about what I liked most. Boring and spoilery. I want you to play the game, not read about it.
Talking about what I liked least. It's not a perfect game. The plot is weirdly off-screen, and the couple of times it's thrust on-screen are the scenes where you're most confused about what you're doing. A couple of the puzzles are underclued, and in one case a puzzle's clues become unavailable (so if you didn't take notes, you're in trouble). But these are not large gripes, and you should still play the game.
Talking about the puzzle difficulty. Worth mentioning. Obduction keeps a tight hold on its puzzle mechanics; there are just a few major ones and most of the puzzles are about understanding them. But the game also exercises restraint about how far to take them. It does not take the Witness tack of "push every mechanic until your brain explodes." The result is a fairly smooth ride (although there are some shaky spots, as I said). There is no "that damn puzzle", which I think we can agree Riven has one of (and Witness has two or two dozen, depending on your mood).
Describing the bugs. Good grief, that's what Steam forums are for. Go wallow if you like.
Talking about the shadow. I admit a desire to go on a tear about the shadow. The Witness gives you, without recourse, a male shadow -- tallish, slender, short hair -- probably Jon Blow -- or if not him, certainly not you. Obduction gives you a choice between two shadows. Is that different? It's not much different.
It would be a great expenditure of effort to import the whole Uru avatar-modelling system with body shape and hairstyles and clothing -- plus height! -- just to model the shadow. Perhaps that's silly. But at this point, offering the choice between a 160-pound male avatar and a 120-pound female one feels like a thoroughly inadequate gesture towards player inclusiveness.
(Yes, it happens that late in Obduction you get an exact readout of your weight. It's not my weight, I'll tell you that.)
And so: This is even less a review than most of my not-really-reviews. I suppose I feel somewhat bruised by today's culture of games discussion, where DID THE DEVELOPER LIE is a more central question than what the game is doing and how well it does it. Also HOW CAN YOU POSSIBLY CHARGE THAT MUCH. And THE BUGS.
I admit the bugs aren't great. (I suffered from the black-page journal bug, and had to hit a wiki to fill in the holes.) But when I look around, I see a bunch of discussion that I want to back right the heck away from. Thus, all these posts I'm not writing.
If you want to know whether Obduction is worth the money, go take a long walk and think about what kind of games you enjoy. If you enjoy environmental puzzle adventure games, play Obduction. And I'll come back and write a review in a few years, when we've all gotten a better idea of how the next generation of adventure games is playing out.
