The departure of Hideo Kojima from Konami saw the publisher react, initially at least, like a spurned lover. There was an ill-advised attempt to remove the creator's name from certain packaging, followed-up by the even more ill-advised spinoff Metal Gear Survive, before things went quiet and, for years and years, Konami did nothing with the company's flagship series.
Time heals all wounds though, and in recent years Konami has been doing a good job of gradually bringing Metal Gear back: first with the Master Collection Volume 1, which brought the first two Metal Gear MSX titles and three Metal Gear Solid games (plus spinoffs) to modern platforms. It didn't launch in the best way, but after a year of patching I'd recommend it wholeheartedly.
