TheDudeLebowski: Finished Obduction, and it's a great adventure game. Can be played both like the original Myst or like today's standard of first-person view.
Although the world created therein is quite astonishing, I kept missing Myst's world more. There's no nostalgia here, as I completed Myst for the first time earlier this year. As with Myst, though, it gets slightly annoying towards the final stretch (a lot of backtracking and repetition), more so than Myst's overlong pod/rail/train puzzle.
Other than that, I enjoyed the game very much, and will remember it fondly. Recommended.
How would you compare it against Myst? In terms of puzzles, difficulty, length, whatever else.
By the way, you know what's next for you in order to keep your momentum... Riven... good luck... haha :)
