C# is awesome, however it has one big issue when it comes to games - garbage collection that can start at any moment and you have no control over it. There are ways to workaround but none is 100%. OTOH from similar level languages there is Swift that does reference counting instead and doesn’t have this problem, albeit has a reference counting problem (where cyclic reference would create a memory leak, but this problem is solvable).
Yep, #metoo, though I started with terminal. I still use GUI but mostly only for visualizing history.
