This has become the game (to date) of which I measure all other adventure/mystery games. Beautiful...
Graphics excel, sound excels, interactivity excels, story excels, puzzles excel, blah-blah-blah. 99.9% of everything I liked about this game. Each Age was just large enough (a little more and inertia would've settled in). Puzzles were just hard enough. Characters were developed to the point I felt empathy towards Atrus' entire family. I felt like the "friend" your character plays. Oh, and a great climatic ending! Fantastic!
So I guess I have to pick one complaint. Here it is--- the puzzles involving sound were too sensitive to error. We knew the solution to a couple of the "monkey" puzzles, but couldn't quite "tune" the instruments. To the point we resorted to the walk-through because we thought we were missing something, only to find it told us the same thing--- just keep trying.
To sum up, (and re-iterate again and again), I loved this game! Thank you Ubisoft Montreal!
