So perhaps ok for people doing a second playthrough for the 'other' side?
Maybe if you don´t mind the money, but I´d say one could make a case for the game actually being worse with the DLC´s content in.
I´ve played through it before it got patched out and positive things I could say about it would be:
a) it utilizes a major character from the first game (he stays on the ship after the quest is over, but you can´t use him as a companion)
b) there´s a fairly meaty dialogue in the beginning that also partially concerns the events in the first game
Risen 2 is really light on ties with the first game so both of the above points adding a bit more sense of continuity between the titles is a good thing.
c) fairly nice weather effects on the added island
d) the added temple is, maybe besides the fire temple, the only somewhat puzzle-y one (though it doesn´t introduce any new elements)
Both of the above are really minor positives.
Other than these, it´s all crap.
The new island is entirely linear and with an exception of one pretty insignificant NPC encounter it´s all just tedious hack´n´slash against one new monster type + few short inane dialogue interceptions in between.
The rest of the quest is also just hack´n´slash, aka kill 18 of these here, kill 5 of these here, etc.
The quest also doesn´t really fit with the rest of the game.
It´s nice to have one more character from the first game in the sequel, but unfortunately the quest he comes with couldn´t be much worse really.
Of all the bigger quest arcs in the game this one is by far the worst and its current price is hilarious.
