Would like to have info regarding steam license

Hello Adobe Substance Designer Team and Community, we are game developers who are trying to make a game (so the questions are in the context of making a game). We had a few questions concerning the Steam license. 

1. Is the Steam license a pro or indie license or doesn't it work like that anymore? 

2. If I buy the Steam license of 2024 and don't buy the newest every year, will I be able to use this version for commercial use (even if it is 2030, for example)

3. (If the pro and indie licenses dont work like that anymore) Are there any limitations to how much you can earn as a buisnis? using Substance Designer for our game assets (for example, when releasing a game). Also, I could not find the terms or document about this, so if there is one, can someone link it for me. 

Much thanks in advance.
