I think for Action RPGs with Co Op System like Diablo with focus of item looting for example those generators are ok, but not for a story telling RPG . I think that really depends on the gameplay.
Size Topic:
You must look which files are realy big. Strong Bad for example has Voices with lot of sound files. That is only possible because their graphics use low toon textures (like Mario 64)
It would be very hard when you try to make a game with a realistic graphic style. That is not recommended. Even normal Wii games have problems then.
My Life as a King has a detailed town with nice looking characters. The managing part is smart, so that they dont need to build real dungeons and monsters. The size would be too big on the one hand and its much more costly.
Yes you right, Omega, a Top Down View is a good way. Because you can use low textures and lower detailed models.
@ KDR The announcement of the announcement that we create a Wiiware title would be a bit too complex for an NDA Violation.
A violoation for example would be, when I put the WiiWare Logo on Screenshots and dont speak with Nintendo before. They want to check the quality. But like World of Goo we work also on a PC version, so its free for us ,how we use our press content.
