For one the game has shown a huge improvement over its predecessor you see games like call of duty that barely look any different from one another then you take a look at this 3089 and its original game 3079 and you can see the major difference just from a single screenshot everything from the terrain to the weapons have been changed, this is a sequel and it shows the major work that has been put into it.
The game went from a voxel box based environment similar to Minecraft to a full 3D based world with curves and edges to match the randomly generated worlds now look a ton different with these new graphics
There's also the fact that that 3089 manages to be a completely different game from everything else out there from the open world exploration to the questing to the creatures both friendly and hostile they all manage a unique sense to them.
3089 manages to be the perfect example of what sequel should be, not just more of the same but making changes and expanding what it should be and as a fan of 3079 it looks like its sequel satisfies both of those needs
oh and grappling hooks nothing beats travelling around the world with grappling hook
