If you liked the looter shooter fun from the first game it's here too - and it's definitely fun -although the base game is much, much shorter then the original. I think I beat it in about 5-7 hours on the highest tier available at the time 16 - and if you start out with your geared up lvl47-50 toon it's way to easy.. I only died on one mid game boss - end boss got one shotted.
I'm now into the end game content: "The Trial of Tarya Gratar" working the last boss there - and it's finally getting challenging (and this is where the meat of the game is at)
The end game will require you to keep upgrading gear to get to the highest tier and defeat it (with much better chance for the best loot drops) but that's part of the fun.
However based on what I've played thus far I don't' think it's worth 35.00 - maybe 20.00/25.
