The Elder Scrolls V

One need not tell too much about this game. In my opinion, the best RPG on the market.
The game world is huge and freely accessible. Quests can be found on every corner and can freely decide whether you first met the numerous side quests the main quest or pursues. The character creation is also free and there are numerous configuration options concerning the appearance of the hero. Geskillt is by exercise of skills.
All around a great game for RPG fans and a must!
