Batman: Arkham City. A game that proved that Asylum wasn't a mere one-off and further showed that with the right team, comic book video games could by GOTY material. It, along with a few other factors, inspired me to make my website.

Spider-Man (2000). Not the first time a superhero was adapted into a video game, but perhaps the first time where it felt like you were the title character. Spidey would get better over the years as tech and design evolved, but it all started here.
