The Elder Scrolls series is one of the highest acclaimed series in gaming history and the fourth installment to the series was the best in my opinion not just was it a diverse and hugely enjoyable game, the graphics were a huge advancement in so many ways, you can control objects throughout your surroundings more than ever. The world in which you find yourself is a world that almost looks like the real thing, it is diverse world of rivers and mountains, there are plains and forests, walled cities and towering ruins. The almost endless tunnels and caves allows for more interesting gameplay and the enemies that you face are scarier and more powerful than ever before, if you haven't played this game yet do!
