Something I would love to see for all of the RM universe is an icon, logo, or trademark that represents RM, any version of it. D&D has the stylized "Dragon-&" symbol. Anyone seeing that knows it represent D&D. On the 3-D modeling websites, there are dozens of prints using that symbol for decorations and worked into the object.
Yes, I.C.E. has the crown, but that's not very indicative of RM. It's an awesome icon for the company. I've printed a couple out and used then in gaming, but it doesn't represent RM, it represents the company that makes RM, in the way that having a FORD T-shirt or key chain doesn't represent the Mustang. The "running pony" represents the Mustang. If i see FORD, it could be any Ford vehicle. If i see the Pony, I know it's Mustang.
I've been printing out a bunch of items for gifts and for gaming and everything (almost everything) has the Dragon-& symbol. I print the items without that logo, but it gets to be bland after a while.
Maybe a stylized "RM" with a dagger? (Mind you... just because my ex-wife's initials are RM, the dagger through the RM in no way reflects my feelings or intentions. LOL) Maybe an "RM" fashioned in the shape of an iron crown? Something that identifies the game we love and consequently, something I can print on my objects, with correct copyright permissions of course.
