A real life take on a video game style that may seem quite inhumane. This is not LARPing.
Players in this game commonly invest in anthills which they connect together via tubing. They then each buy a different species of ant and put them in the anthills, with "resources", like food. Each species of ant then goes about building their colony until they come into conflict with another species, which they will instinctively attack. The goal of this game is total eradication of the other ant species.
"Hey man, wanna real life rts with us next month?? We're getting the big African ants!"
"Sorry, I'm not really into small-time genocide."
