Lag is definitely a problem. I was trying out the new option to have a save anyone can access even when I’m not on to host but oh boy we had to take a break and go play OG Grounded again because of lag. Even as host on Steam I had lag. Oh and some of the items were falling below the ground occasionally.
However! With what I saw as upgrades to the original in terms of tool use, enemies and such, I was extremely pleased with the direction they are taking the sequel.
Honestly because of the studio’s history I’m way more confident in seeing these things fixed than I would be with things made by others. They have a good track record.
