archive.org has 6,581 game entries with a myriad of helpful materials available such as pictures, videos, license status, dates, authors, history, reviews. And they've settled into offering game access via some sort of emulation (optional fullscreen, its just like being there, [b]it even works on Android Chrome) which has been tested in the real world (Console Classix) and is legally solid thanks to a few DMCA clauses (originally designed to restrict; now cleverly flipped) and court decisions.

Linking Wikipedia is sometimes problematic if you happen to link to not very explicit redirect link for a thing (like if a game by same name appears or the game name is taken over by article about the actual subject relating to the game's name), as they can move them around without leaving link to the old thing to where they moved it. Otherwise both are OK in my opinion.
They expect humans to know to view the edit history. Seems to me a bot could pull it off too. I dont care so much to have wikipedia xrefs as others but it is good for improving UVL popularity
