Godot on Steam

The only benefit I can think of would be auto updates (if you want that), I don't think the engine itself works any differently depending on where you get it.

soundgnome I would say auto updates are a disadvantage. Just download from the website and keep them in your godot folder. That way it's easy to test different versions.

The only benefit is leaving a review, so you can tell everyone you love godot with only 2 minutes of playtime.

At first you start using Godot on Steam, then later on you start using Godot from website to test that new hotness, Dev snapshots. In the end, all of those aren't enough and you ended up using Godot from source... went ham and doing something like this https://mastodon.gamedev.place/@0/110751815637321808

But that thirsts doesn't seems to end, as you continue to stitch your Godot, it has become sort of frankenGodot

Templates i believe come with the Steam version, as well as the freedom to swap versions at any point from 2.0 up to the latest version. There is also auto updating so you will always be able to swap to the latest version at any point even if you locked yourself to say 3.5 for the last 6 months.

The cons could be auto updating if you don't pay attention and accidentally upgrade your project, and no C# support which is negligible if you only use GDScript.
