Microsoft has decided to be a little generous this month and is offering all Xbox LIVE Silver members the chance to trial four free days of Xbox LIVE Gold, from 23rd to 26th November, as part of an event being called Xtival. Silver members will have full access to complete Gold functionality, with Microsoft promising a number of bonuses including competitions and exclusive downloads. Current Xbox LIVE Gold members are also being promised a treat, although Microsoft is yet to announce any specific details. This should give all Xbox 360 owners in Europe the chance to trial Xbox LIVE Gold if they're undecided about whether it's worth paying for or not.
