FNAF2 Is a pretty good follow up to FNAF1. There are more enemies and more mechanics, but the doors are gone. The game is remarkably less scary than the first FNAF and I the biggest reason is the lighting. FNAF2 is a pretty bright game and you're never in the dark or worried of what lurks beneath, especially with the flashlight. All of the animatronic designs moreso lead to good character models rather than monsters to be terrified of. The death animations and things you see are borderline cartoonish. The gameplay loop like FNAF1 is challenging and interesting at first but becomes almost mindlessly repetitive by the Night 3 and beyond. It's just vent check, hall check, music box, mask, repeat - until 6AM. Thanks to the music box mechanic, you're incentivized to NEVER look around the rest of the building. The first game had this issue but that was due to the power limitations. FNAF2 despite these complaints can actually be a fun play for your first run and taking a shot at the custom night options. This game's 10/20 mode cemented the series' legacy for insanely difficult final challenges for players to overcome. Some players like DJ Sterf have up to 4 hours of watchable guides on tackling this mode. FNAF2's legacy is pretty big for the franchise as I see it as the first extreme takeoff of popularity thanks to the likes of Markiplier, Game Theory, and the many other Lets Players and youtubers going after FNAF. FNAF2 left behind a good legacy with a decent game in its wake.
