Games was worthless? How so? Games are usually for entertainment, and for me it did just that... opinion mind.
Pokemon Stadium 3 - cough PBR? It IS stadium, only with Wi Fi, and no minigames.
Snap 2 - well, it's different to an RPG like the Shadow Pokemon games- a spinoff, but I'd admit number one was fun (and good chance to use the Wii remote as well for it).
Mystery ungeon on Wii - somehow I doubt it, more than likely to stay on the GBA/DS. Shadow Poke game probably more likely.
Ok i admit the Shadow Pokemon games arn't completly worthless, i am starting to find Colosseum to be an ok game (Purifiying Pokemon is slow as hell though), but even so there is no reason at all to make a 3rd one(seeing how we can now get all Johto pokemon) unless Nintendo are getting really short on ideas.
Are you crazy PBR was nothing like Stadium all PBR had was Battle the Colosseum Masters, Battle your battle passes, battle on Wifi, & DS battle where as Pokemon Stadium had, Gym Leader Tower, The Pokemon Cups (and if i remember there was 5 of them), Free for all, Minigames, ability to play GB/C Pokemon Games on tv, create your own Battle Pass instead of getting set ones, now if all that was in it and they had Wifi then it could be classed as Stadium 3 but as it stands it is nothing like it.
I would really like Snap 2 but it will most likely never happen :( due to the first one only been made to see what Pokemon would be like in 3d.
I think Mystery Dungeon on the Wii isn't as unlikely an idea as you think i mean the sales rates have been good for the first two and look:
Red Rescue Team-GBA/Blue Rescue Team-DS
Explorers of Time/Darkness-DS
why where they done like that? so they could connect, but people will only buy one copy of the games unlike with D/P, where as if they had done this
Explorers of Time-DS/Explorers of Darkness-Wii
and they connect them the same way they connected them on the DS more people would have thought to buy both because one would be a 3D game that they could play at home and one would have been a topdown game that could be played while on the move and then you could transfer items that where collected while you were out and send them to your Wii and that is how Nintendo makes there money with Pokemon it there ability to sell one person mulitple copies of one game, e.g Red,Blue/Green,Yellow,FireRed,LeafGreen they are all the same game (minus some Pokemon and the sevi islands) and most Pokemon fans own most if not all of them.
