After picking up Darksiders for $5 during the most recent Steam sale I completed the game after putting in a touch under 20 hours. With my adult brain I can finally say, "That is this is Zelda I love Zelda games" and I'm greatly encourage to try can go back and complete some of classics in the Zelda series.
I enjoyed the combat and puzzle solving in Darksiders. The combat in the early game can be a bit of a button smash fest on the X button (with an Xbox controller) but by the end combos, secondary weapons, and upgraded abilities will all be required to finish off the increasing difficulty of enemy mobs.
The puzzle were challenging, and most of them can be completed assuming a player examines all the features in a room carefully. However some of the puzzle are incredibly difficult to complete even if a player figures out the solution since some of the timing puzzle require quick hands to juggle abilities. There was at least one instance where I didn't even know one of my abilities could be used in a particular way thus leading me to waste half and hour of trying to figure out a different solution.
All overall the game was definitely worth my time and at $5 (on sale) the value can't be beat. I would highly recommend the game even at its current Steam price of $20
