World of Tanks

So I have been trying out a few free to play models and I came across World of Tanks.  This game is one where  players participate in short tank battles over and over again.  The player earns experience and money through these battles which allows them to research and purchase higher quality and more powerful tanks and equipment.   There is also a currency that can be purchased with real money which gives players access to specialized equipment or premium memberships.  I feel that there is very little in the way of socializing in this MMO as the vast majority of battles are random battles with complete strangers.  The draw that I can see would be the idea of progress and the desire to get the best of the best so that one can easily destroy the opposing tanks.  With a system of horizontal leveling that I am proposing the idea of progress will still be there, but not as strong a driving force since everyone will still be on a level playing field.  The desire to win and dominate will still be a driving for many since the competition will still be there, they just won't get a large advantage because they have been playing longer.  Also I think that having teamwork being essential that people will be drawn by the social aspects of the game.  I might have to figure out a way to add in special items that can be purchased for real money as a way to support the game.
