For 40k, I’ve been watching a lot of bricky (also does non warhammer stuff so I’ve linked a specific video) and krakduk. (does the annoying youtuber voice, if that gets on your nerves it might not be the channel for you)
There is also the lexicanum for everything 40k, old fantasy, and age of sigmar.






If you can still use a mouse well, grand strategy games can be played with one hand. Despite all the (deserved) criticism they get, paradox games are a lot of fun. (and their modern ones even feel like a full game without having to buy any dlc) They can be a bit difficult to keep up with without a keyboard though so play on lower speeds.
If you are more concious about who you give your money to, endless legend 2 is a 4x published by hooded horse that is very good (think civ but fantasy) and since it is turn based it is a lot easier to play with just a mouse.
