The Legend of Zelda: Twilight Princess
My statements about post-game collectibles may have been slightly exaggerated. Though Twilight Princess is significantly long, the vast majority of that game length is the core game - questing around, solving dungeons, felling boss monsters. Personally I don't see anything wrong with that, since there is still as much to do outside the game as your average Zelda, maybe slightly more since this time around there are 5 heart pieces to a container.
There are some things with the game that could be improved upon, to be sure; for instance, after the first dungeon, there is a complete flood of rupees, filling Link's pockets before you know what's happening. And some methods of speedy transportation come long after they would be considered useful. But in spite of these, Twilight Princess is an amazingly epic adventure and wildly great fun to play. (See previous statements.)
Progress: Killed boss, 20 heart containers
