Here's a little UI/UX design I made for a video game project.
The biggest difficulty was to synthetize visualy the large amount of content and information needed for the player. I rely on the work made by Raphael Quercy to keep something consistant and coherent between the web portal, the ingame visuals and the art direction.
It was a really good experience. Everyone was open minded, willing to build the best. I was able to make suggestion to the ergonomy and modify the visuals in consequence. The game has never been shipped but I whish I'll have more experience like this one in the future ;)
Technically I was able to focus on designing visuals in Photoshop with someone to focus on integration after me. But I really took care of building as much efficient photoshop files so they could use them easily to crop images and content whithout surprises like strange behaviour while merging layers with transparent effects.
