Hmm, judging from the downvotes it appears my comment relied on some sort of industry knowledge people don't know about perhaps?
Rockstar is the studio formerly known as DMA Designs. DMA Designs is/was a british studio. DMA later changed their name to Rockstar. At one point yes, a subsidiary of Rockstar created GTA.
Rockstar was later purchased by Take-Two. This was during the era publishers often strong armed their developers into acquisitions so no doubt there was some bullying involved. Take-Two receives a large portion of the major UK games development subsidy pot[1].
Take-Two has now, as per this article, buying yet another UK devloper/publisher. The UK games industry is getting hollowed out. All while the UK public is subsidizing the very companies performing the surgery.
