These were two My Little Pony cake toppers that I personally customized. It took about 3 months to finish the pair- mostly because of the bride pony! Here is a picture of them on our wedding cake.
It's been awhile since I've seen a video game wedding cake, so here is the cake my husband and I had at our wedding. The characters are Squall and Rinoa from Final Fantasy VIII... Go forth and caption. :)
This is the cake we had at our wedding, when it came time to cut the cake the groom actually pulled the master sword out of the top to cut it :)
