Personally I enjoy the complicated character building of Grim Dawn way more than the item hunting. This also means I will play a host of characters and eventually complete item sets and have the resources for crafting after half-completed character number 86. For me the grinding is mostly a test on the efficiency of my build.

Maybe look into Warhammer: Chaosbane. It has a point system that superficialy looks similar to Grim Dawns devotions or Path of Exile, but in reality it’s super simple. And while you do collect items, they don’t matter as much as in other ARPGs. The flip side is that it’s kinda hard to fail because the game is so simple.

Maybe it’s just me but I think the Mumble UI is way better than the Discord UI

Is JavaScript a serious language? /s

Joking aside: One of Brendan Eich’s books probably contains something resembling a style guide.

Since you specifically mentioned C# : https://learn.microsoft.com/en-us/dotnet/csharp/fundamentals/coding-style/coding-conventions

I’d be surprised if there is a serious language that doesn’t come with at least some semi-official style guide. But usually they are not universally followed and everybody just does their own thing.
