I love this game! I actually took some vacation time, so that I could start playing as soon as it came out. There were a few nights where no sleep was got. I just didn't want to stop.
Right from the beginning, I appreciated the unfolding of the story, the additional new abilities; most notably, climbing, and just everything. It's not just about fighting. There's a story being told, and a princess to rescue.
You start the game mostly naked, and your accumulated wealth will give you the ability to acquire different clothing. As you explore more of the world, you discover ways to display your world map. (my son decided to play the entire game without activating the world maps - drove me crazy) You have the ability to play the harder setting, but I didn't enjoy that so much. The baddies were a lot harder to beat, and I'm not really a fan of the fighting.
I enjoyed the puzzles, as well as the exploring required to find as many of the mystery bonus items as I could. The downloadable content was well worth it. I wanted more gameplay, and I got it.
It doesn't surprise me that the game continues to be so popular. I've restarted it several times already, and will do so again. Have fun gaming.
