Dude, this is old news if you keep up with the evolution and history of Rockstar, or have been a gamer for some time, hopefully you read up on some of the gaming history, but in short, Rockstar Games is the brainchild of Sam Houser and his brother Dan Houser, they left BMG Multimedia positions to take over from DMA of Scotland, where at that time, GTA was born, Lemmings was born, Race and Chase was born, among other IP.
The company grew to some extent at the time under the auspices of Wunderkind David Jones. Lemmings in some ways inspired GTA with the ability to have many moving creatures or things on the computer screen at any given time, the birth of 'smart AI' in some ways.
The Houser's background differs from that of DMA founder David Jones, that's why the early DMA is primarily PC based titles. For Rockstar, it's always had a focus on consoles because the Housers were raised on those games, as was I.
I'm still a person who doesn't invalidate PC gaming, and no one should, but the fact remains that consoles are so much easier to cater to, no matter what anyone in the PC realm thinks. The hardware is vastly different on the user end, in console gaming, the only hardware issues are from the competing companies offering their own handheld or console platforms
