hi guys is this game like rust that u build a base and there's a wipe? or can I play singleplayer and just come back in after months and see my base still there? thanks for answers

You can, ther's probably no wipe.
But there's a chance you need do restart anyway in order to use/enjoy new content.
Especially if you've got revealed the entire map already.
New ressources and map-changes (of future updates) only appear on undiscovered land.

Another thing you should keep in mind is technologies. They might probably not work in the way any more like they used to work in the past.
For example: During the first updates you were able baking bread in a kettle. Then they added an oven in the game ind since then you have to use this one in order to get bread now.

But overall, devs did a good job avoiding wipes so far. But sooner or later you have to start over if you want to enjoy everything the game offers.

Why and how would they wipe worlds that are saved on your computer? Like I said that isn't going to happen.

No wipe, but there's a chance your world is no longer supported by new versions of the game - basically the same result.
