This was something that just occured to me, and I think it should be brought up. We have european release dates, yet most of these are in fact just the release dates in the UK, and many times, mainland Europe gets a game earlier than the UK. God of War 3 just released in mainland Europe for example, but it isn't out in the UK until friday, which is the date we have on the frontpage.

So, what should we do?

Both, obviously.
The database junkies will make a killing thanks to that :P

Write UK, it's the simplest solution, and the majority of our European members are, as would be expected, from the country with the highest English-speaking population.

We could add EU dates for everything, but it's a lot of extra work.

Option A.
Not all of the dates are for the UK simply because not all of the games are coming out in the UK or a game is getting a WAY earlier release in an other european country.
Absolute 'Mainland' dates don't exist.
Games don't get the same release dates throughout dozens of european countries and publishers for the different countries seem to deciding at will if the first known official date is the actual release date or not i.e. games get delayed or even preponed (sometimes very, very shortly before their last known date).
