Over 10,000 Classic Amiga Games And Applications Available To Play Online Courtesy Of Internet Archive
These are all playable in your web browser, though performance varies depending on which one you're running. In our limited testing, games seemed to work best in Firefox and felt a little slow in Chrome and Edge. There's also the issue of figuring out keyboard controls without any instructions, especially if it's your first time playing a game and you have no idea what maneuvers are available.
So it's not perfect, but you can't beat the price—free! The catalog is pretty extensive too, with games like Bubble Bobble, R Type, Double Dragon, Batman The Movie, Lemmings Holiday, Street Gang, Ninja Mission, and plenty more. And on the non-gaming side, you have titles such as Deluxe Paint IV 4.0 and Lotus 123 version 1.0.
While extensive, the catalog of titles isn't all-inclusive. There are some notable omissions, such as Sid Meier's Civilization. You might also run into duplicates, such as 3615 Load (it's in there twice), as well as different version numbers of the same game.
One piece of advice—be patient when loading a game. Many of the games take a bit to load and because the playable section of the browser goes dark, it can look like something went wrong. Just hang tight, chances are the game just hasn't finished loading.
