This has kept me occupied for a month. The quests are challenging without being impossible. The story is interesting and there is just enough difference to stop it being a rehash of Oblivion, whilst still being familiar enough to feel part of the canon. Haven't finished it yet - but loving every hour I spend. If I work out how much this is costing me an hour by dividing the purchase price over the number of hours played, it's cheaper than chewing gum. Fantastic.
