I'll be updating RE2 probably later today and then you can take a look at the update notes and decide.

I only started like 3 days ago and haven't progress far.

Is new world going to affect the RE2 with those new POI, starter planet, galaxy rework?
Should I wait for RE2 update or it's insignificant enough to ignore and just play?

RE2 has now been updated. In the change notes it shows what only shows up in a new save.

Thank you, worth start new world to me.

Is there a way to transfer a playfield from the old version to the new update? I'm only on the part of the story where you leave the planet for the first time, but spent ages digging out a base in a mountain and would rather keep it for the playthrough.

No sorry.

Given the new RE2 update, it is best to start with a new save, there is a way to keep the players and their lore structures on the new save

First off: RE2 is effing amazing. Thank you so much for all the hard work!!!
Since I discovered Empyrion and especially RE2 I spent a ton of time with this game. It's sad having to start a complete new save for experiencing all changes although I understand the technical reasons. However - in hope posting external links is allowed - I'm currently trying to transfer at least my ships and items to the new save using this video: https://www.youtube.com/watch?v=6GXhiBE8pXA
At least something. But I wouldn't dare to transfer the player progress, PDA or reputation since I don't know how that might affect the new save.
I hope this helps a bit for anyone who wonders the same.
(edit: Worked. I only used the ship for transferring items. After that I spawned a new one and deleted the previous one. Due to the update some items/blocks changed. So the previous ship had weird textures and false blocks, like a wind turbine... XD)
