It appears that Activision is just pissing everyone off nowadays, first Infinity Ward and now Greg Hastings. Greg Hastings is a major player in the advertising of his game franchise. He goes to demo events, E3, and probably tells everyone about it at paintball events. Activision believed otherwise.
“I had to fire Activision for doing such a poor job. Activision tried to steal my franchise. Within 24 hours of me shipping my PlayStation 2 game, Greg Hastings Tournament Paintball Max’d, they sent me a letter and they said, ‘We feel you’ve abandoned your franchise, and we’re going to commence making games called Greg Hastings Paintball without Greg Hastings.’”
“A billion-dollar company tried to steal my identity, and I was able to fight and regain my identity.”
