I wanted to see if I could create something that is emotional between people. Existing games are about killing each other or killing something together. The idea of social emotion means people need to share feelings. At that moment, the players are in sync. The problem [with many games] is there's no chance to share emotion. Most of them are busy, [there are] explosions everywhere. So we got rid of all the background noise and we had to get rid of the guns.
