A dinner party doesn’t have to be a formal affair. There’s no reason why every guest should arrive in formal wear, or point the pinky finger when they sip drinks, or speak in a clipped ‘Queen’s English’ around the dinner table. You want your guests to behave, but they don’t have to be so prim and proper.
Let’s be honest, if I was hosting an entirely formal dinner party, most videogame characters wouldn’t get an invite. As loveable and iconic as so many virtual characters tend to be, most of them are ‘rough around the edges’. Minecraft Steve eats food by violently ramming it into the centre of his face. I adore Raziel from Soul Reaver but his diet consists mainly of human souls; his eating habits would put the other guests off their food. Most characters lack the ability to actually sit down, which would make an evening meal quite uncomfortable.
