Hi, welcome to A.Org!
You may also find that your game disks are designed to be run by rebooting the Amiga with the disk in the drive, rather than from the Workbench environment.
Not sure how familiar you are with the Amiga, but in case you don't know, pressing CTRL, left-Amiga and right-Amiga causes a reboot (the "Amiga" keys are the ones with "A" on them in the Amiga typeface, next to the "Alt" keys).
So to run your games, switch on the Amiga, insert the game disk, wait for any disk activity to stop, then reboot and the game should load.
