A lot of the cake toppers that I make are for gamers. For the most part, these are for fans of various videogames.
But I also do cake toppers for fans of tabletop roleplaying games. I always love these, perhaps because I met my own wife at a weekly D20 game.
The first one I did had the couple snuggling, with some character sheets and dice on the ground next to them.
The second couple I did like this were to be sitting at their coffee table (couches are very comfortable for RPGs- sometimes too comfy, actually).
Also, the groom ditched his suit quite early this time, and wanted me to match the logo on his t-shirt instead. While the bride kept her dress on for game.
