80% complete right now and Horizon just keeps getting better. It's not perfect, but holds its own for an original.
Had a good laugh when I came across "Zavala" from Destiny. Made me wonder if the Cauldrons and Rasputin war bunkers/Dino's and the Traveler/Corruption and Siva, all have something in common. Not really, but there's some similarities.
With the old texts and data points mentioning more dino's to the west, and something about a massive dead lake, I would have to imagine if there is a Horizon 2, that it could be set near Salt Lake City, Utah, considering Horizon is basically set near Denver, Colorado. I can't wait for the Frozen Wilds DLC and a possible sequel.
