I really hope that Karma will be added at least 3 years later, cuz I`m still waiting. This will add a little more realism to the game.
You know how great it is. This is like a reputation in real life. But, in real life we can know reputation from a review on the Internet, and here for this there will be Karma. So recently I was looking for one of the best resume writing services and found a review on this website. Karma for sites, lol. Some service wrote a good resume - got a good review. Fair enough. You can also implement Karma in the game. Let the other players still write comments about each other. It will be fun.
