Is it a good idea to buy now..? In my opinion the game as it is now is well worth the double. Should it be looked as some sort of investment for the future and what the game will become? Not in my opinion. No one knows when or if the game will be finished. The prognosis is good, again in my opinion, but no one knows. By my estimate we'll see Valheim being out of early access in 2-3 years from now. Could be sooner or later.

Tl:dr: Only buy early access Valheim if you believe you think it's worth your money currently. It's continuously being updated, but some/many thinks it's going too slowly. Me - I'm a satisfied customer since several hundred hours back.
