I was searching for Secret Agent's wiki page and apparently its first release was 2013; the game was actually released in 1992. It seems the search bar is taking data from the releases section; in the case of Secret Agent, the only release that's filled out is the 2013 GOG release, so it ends up showing that the game was first released this year.
I can understand why it would be programmed this way, but this is just broken. There's a bunch of games with newer release dates that override the correct initial release year. Another example I saw was Duke Nukem 1, which was allegedly first released in 1998, rather than 1991.
