It's not really possible for anyone to "prove you wrong" because whether or not you find anything that you think is valuable in the update is going to be entirely down to you. Speculation & questions up till then is all that can really happen.

So, really you'll be the only one capable of proving yourself right or wrong depending on your experience playing after the 16th.

Hearth & Home has been the planned first update since the game was launched into Early Access in Feb & there will be other updates in future with other content. If you've been enjoying playing the game up till now, some future update will add more content you'll enjoy at the time.

So while it may be "game over" for you after Hearth & Home drops, hopefully you'll see some future content you like and play it again.

I usually go play other games while I keep EA games I'm supporting on the back burner, and pick them up when they get to a state I am interested in diving into. When H&H drops I'll be back in Valheim and starting a new seed!

Till then I'm taking a VH break & doing a deep dive back into No Man's Sky :)

Edit: Also that is a sweet build, nice work! You may enjoy Hearth & Home more than you're expecting from the looks of it.
