Last Epoch is a phenomenal game and was worth every penny years ago--I'm incredibly excited for the 1.0 release. It's got just the right amount of build complexity--if making a Path of Exile build from scratch takes a PhD, then doing it in Last Epoch would be like community college (although there's definitely differences in complexity from class to class).
The developers (Eleventh Hour Games) offer regional pricing, so non-Americans aren't priced out of the game, and although servers for online play will be available based on a cost vs demand basis, it is possible to play the game 100% offline.
If anyone has any questions about the game, let me know!
