Hub43 solves two problems for social game players. The first problem is that, in current social games like Farmville, the game you play from your notebook is different than the game you play from your phone. While it may provide similar graphics; your game world is completely different. Hub43 games are truly cross platform, the same game runs on all devices while taking into consideration the client screen size.
The second problem is that the social interaction between players is limited to exchanging game elements with no real-time actions. In Hub43 games, when a player moves his character from his phone, another player logged in the game from a tablet would see the character moving the same instance the player starts to move.
