I can see where he's coming from, but IMO nostalgia isn't what's ruining games. What's ruining games is developers using nostalgia incorrectly. That's why Sonic Forces fails IMO. Not only did they waste nostalgia( you never fight Chaos or Shadow, and Metal Sonic is a fucking quick time event) it's also just not fun. The reason Sonic Mania works is because it takes nostalgic locations and does something with them. The reason the N Sane Trilogy works is not because they abused nostalgia but instead because they took the originals and made them look and sound better(for the most part). Neither of these games are perfect, but they used nostalgia correctly. They breathed new life into old game series and made an entirely different experience. Sonic Forces doesn't do that, it takes old characters and environments and does nothing new at all with. It just makes them worse.
