I still haven't heard a response to why Sonic Colors should not be called Sonic: Colors or why Sonic Boom is not Sonic: Boom.
How about Metroid Prime?
How about Donkey Kong Country on the SNES?
A final one, Mega Man Battle Network 6.
From me, it is because they should be used in those cases.
And on the topic of Mega Man, a ton of games on the GC and GBA have no space between Mega and Man! So shouldn't the titles dor these games be Megaman? We know that the official name is "Mega Man" but because it's not represented that way on the box, why not Megaman?
In these cases, such as Mega Man X6 on PlayStation, the title should be Megaman X6, and have Mega Man X6 in alt-title. I know that it is Mega Man, and it says Mega Man in the copyright info and maybe it has Mega Man on the spine, but that is not what is on the cover. Having the other name in alt-name will solve any search issues. It can be put into the Description field that the name has no space on the cover. This is also why so many people will type it without the space, it is not because it is some comon typo, but it is because Capcom has actually used that name on their products.
But am I saying we should all go and change the Mega Man and DKC and Metroid Prime entries? No, there is other work that is more important than having to pretty up everything. If/when we get the different name fields, then that would definately be the time to go about doing that.
