With a small team of 270, they were able to create what I believe to the be best MMORPG in existence. Quality + Quantity
Combat is intensive, and with the addition of dynamic events there is never a dull moment in the game; there is always something to keep you going (Such as dungeons, heart quests, achievements, and a customized personal story).
Graphic wise, it is a massive, interactive masterpiece.
The extreme detail placed into a game so massive just shows how much work was put into it.
In addition to the amazing game play, its lore is worth looking into deeply. This makes it more of a world than a game.
Instead of being released,Tyria opened its borders. Well done ArenaNet, thank you for showing us how it's done. Quality and quantity at a perfect equilibrium. I would give this game an 11 if I could.
