An actual interesting article would be on the tax credits themselves and if they were a good idea. It seemed to me, as someone who worked in the games industry, they were a good idea but came 5-10 years too late as by the time they were available the majority the UK's triple A game industry had collapsed and large amounts talent was brain drained off mostly to Canada but also Europe and America.
Maybe 30% of the people I started with no longer work in UK and haven't for years. And I was the same I've only recently come back (terrible timing on my part considering what's happening in the UK at the macro level but that's a different story!). In fact one of my coworkers who _did_ stay works at Rockstar North on the GTA titles.
Canada had a tax credit scheme for games companies that the UK was unable to react effectively to. Again an actual interesting article might ask if UK games companies collapsed due to inability to react to the market or because they moved, or couldn't compete internationally for talent due to other countries having better tax environments.
