I've got all the DLC (including deluxe), and have my money saved to buy as many more as frontier can come up with!
I'm not really a reviewer, but I've written positive reviews for the base game and the South East Asia Animal Pack DLC. I went out of my way to review that one because my perspective was so different (positive) from what others were saying that I felt like there was something original for my to contribute, from the perspective of someone who plays the management side of things and wants more animals.
I love the other dlc's too, but haven't done reviews because I don't feel like I have anything original that hasn't already been covered by others. That may be the wrong way to think about things -- if people are mostly just looking at the number of thumbs up vs. thumbs down -- But I know when I read reviews, I'm looking for new insights, rather than just a tally. But again, maybe that's the wrong way to think about these and I should go back and write something positive for each one.
