Hi there,
Haven't been active in here for a while, but recently (just this weekend), I produced a multiplayer pong for a gamejam (#MultiJamUltra2015)
The story behind this is that I was (still am) struggling to make a popular multiplayer game. One of the problems with indie multiplayer games is that if there are not enough people people to play, the game is kinda dead.
I ponder more about the meaning of a social game. Something as simple as
pressing a button can gather almost a million active users, yet it's so difficult to get a multiplayer indie game popular.
I then come up with an idea of making a very simple game (pong) multiplayer, and add some political flair to it. More details here:
