Hi,
I am looking for answer to question: do I need a Plus plan if I intent only to sell models on Asset Store. I am not going to publish a game or app using Unity.
No.
What about $200K limit? Does it also refers to asset store?
Yes… I’m pretty sure the $200k is not specific to games but includes asset development/sales as well. But until you hit that mark, you should be ok with personal license.
