Remnant II certainly is more Remnant, but it's by no means resting on its laurels. There are some big changes coming to core elements of the experience - from class design to visuals to procedural generation and more. Based on my hands-on time with it, all the new stuff is paying off - big time.
As for me, I really really loved Remnant 1 and got all expansions for it gladly. I'm also a big fan of Gunfire Games studio and their other AA games like Darksiders and have high hopes for Remnant 2.
I haven't fully watched the video yet but it seems like the sequel improves on the original in pretty much every way while not being just a lazy continuation and instead having actual gameplay changes and improvements.
I'm so excited for it. Loved the first one playing with a buddy. First game I ever did a hardcore run for. So ready for release
