You lost me at "we have a Youtube channel"

They are using in game voice chat, maybe they can't hear you because your mic is not working, or you are in a party yourself

if you enjoy RPG I would also recommend Dragon Age Inquisition, a great game.

or at least Fable Anniversary

Mine was Deus Ex Mankind Divided, followed by Dishonored, now is Mass Effect: Andromeda

Deus Ex Mankind Divided, The Witcher 3 Wild Hunt, Gears of War 4, Doom, Forza Horizon 3, Fallout 4 are some of my recommendations

Splinter Cell Chaos Theory 'nuff said

Grand Theft Auto V and IV, I tried a couple times but I cannot get into it

I most of the time go for the "hardcore" difficulty setting, depending on the game, on some I jump straight to the highest setting, on sports games I try to set the difficulty to the one closest to simulation.
