"The creative minds will not go away"? From the two games he mentioned one has slowly trickled down to a mere footnote of its former glory (Tomb Raider) and the Grand Theft Auto's developers have migrated to the US and have been creating their ongoing masterpiece commenting on US life and politics in a marvelous manner.
And anyway great games are steadily being produced from many countries in Europe (Sweden's DICE, Germany's CRYTEK and so on) and an additional huge bulk is made in the US but not so much from Britain anymore.
It would be wise to actually agknowledge the sad reality of it in order to find ways to remedy this apart from mere wishful thinking.
