one of the things about GTA 4 that I loved was that Niko interacted with traditional crime organizations such as the Russians, the Irish mob, the Jamaicans, the Cosa Nostra etc. I always enjoyed that seeing the different criminal cultures. GTA V kind of went a different way with being based on robberies, but also it tended to be focus on government shenanigans. I hope GTA 6 goes back to the gta 4 style focused on various gangs
