I have been playing Skyrim for a couple years now and I think is a great game to play. Skyrim is an RPG game where you (your character) are the Dragonborn, which is the only person who can kill dragons by absorbing their soul. Your main objective is to defeat the leader of the dragons, Alduin the World Eater, in Soverngard (which is the place where the people go when they die).
You can choose to play as any of the following races: Khajiit, Redguard, Nord, Imperial, Orc, Argonian, Breton, High Elf, Dark Elf, and Wood Elf. Each race has a racial specific spell they can use to help them in combat. Unlike other RPGs you do not actually pick your class.
There are two ways to gain experience. You can either explore and kill monsters and humanoids or you can complete the main quests. You can actually purchase an update that gives you a quest line to adopt kids as well as other features. There was an update in 2013 that removed the level cap. Meaning, once you have defeated Alduin and the primary objective for the game is complete. You can continue to quest, gain experience, and collect better equipment.
Anyway, when I completed the game, I really enjoyed the overall experience. It is a very detailed world and the graphics look very realistic. In my opinion I feel that Skyrim is one of the best RPG games ever created. If you have not played it you really should. You are missing out.
