I realize it may occasionally seem like a tug of war with me and my sometimes manic game entry sprees, but there has been some miscommunication on this one. There is a difference between the two titles XIII and XIII Classic. They are separate entries on GOG and Steam. They should be a separate entry here as well. I just tried entering both XIII and XIII Classic into the Search box and nothing came up that matched what is found at the provided link of my request. I saved screen shots of this failed attempt.

I'm not an expert on XIII, but from what I see on Steam, comparing XIII and XIII Classic, wouldn't XIII be listed as XIII (2020) here and XIII Classic as XIII (2003)?

Everything I see when searching information on these games seems to point to that being the case. Again, though, I don't know much about these games, so I'm trusting the always-correct internet. :)

P.S. I don't see the point in separating. Edition added on game page.
