Why not give it to the t_catt? It'd be really nice for a memento, and could be a 'thank you for the [site]'
As for the design, there's a few routes you could go.
You could make the panels like individual rooms in the inn, with people featured chatting/playing/dressed up as characters/fighting dragons/stealing treasure/stab the buddy...
The other route would be to make it kind of scroll like, where individual panels have a variety of scenes from various games... could have heartwarming scenes, combat scenes, other sorts of scenes. Maybe even make it a 'patchwork story', where you take the scenes from various games, insert say characters to make it contiguous between panels, and then make a story/myth with them.
The first idea focuses on the people, and the second idea focuses on the stories. Just a couple ideas from a butterfly.
