I believe the following additions will make the Arcade a little more engaging:
1 - In addition to having a link to the "Last Played" game (as it currently is on the Arcade index page), have the picture of the game displayed in place of the game category image.
In other words, instead of displaying category images, have the image of the last game played show. This will keep the Arcade page looking new and engaging.
2 - On the member's Profile page (as seen by other members/public), display the name and image of the last x-amount of games that the respective member played.
The attached image will give you an idea of what I'm talking about... The image I attached contains my "Friends"... but picture it with the game images instead (I'm referring to the long horizontal line of images).
