Definitely not because it is a different engine from 20 years ago. This is coding shit but two different engines are like two different languages. You can't create a sentence combining english and portuguese and expect it to make sense.
However what they can do as obsidian and "recreate" the BG world with updated graphics. Which is not what they did in the pre-alpha.
poe2 graphics looks really beautiful. the only thing i hated it was that it's 2D. i would have like it much more if it's fully rotatable 3D. but that's not the main problem. the main problem for me is that they don't follow basic core rules.
the game on day 1 is totally different 3 months later. every few months all they did was keep nerfing without adding anything. all the builds created by the community has gone to waste as it doesn't work anymore. what they did was just checking on the forums on veteran builds. then they just nerf them. every single time. up to a point that the game became a boredom for me.
