Seriously, best of luck guys. Don't say you weren't warned when you're hit with a cease & desist from SEGA.
I do sales & marketing work, i have an entire team dedicated to working on ads, websites, images, etc for our Company. If anyone used any of our images without contacting me or anyone in my team directly, i'd sue em.
Let me put this in other terms. If someone, let's say, in Customer Service authorized the usage of our images. Without my or other Manager's consent, there's a good chance they would get fired. I doubt any intern has that much pull at SEGA, good chance you'll get them canned as well.
