A while back, XGen Studios announced point and click adventure Machinarium would be coming to WiiWare. Since then, it all went a bit quiet and it certainly seemed as if the game had been scrapped.
Sadly, it's now most likely true, with Aminita Design's Jakub Dvorský discussing his dislikes about the Wii. This was recently revealed in an interview with Eurogamer, where the company talked about bringing their latest project (Samorost 3) to as many platforms as possible, as long as they were powerful enough. It was then Dvorský stated that he didn't like Wii or WiiWare due to it's limitations.
We don't like Wii because the resolution is so low and there is a size limit on WiiWare of 40MB, which is so low for nowadays, It's crazy.
However, Aminita Design are looking into Wii U development and have claimed it looks promising. It's suggested that Samorost 3 may come to the platform, so perhaps Machinarium will still make an appearance on a Nintendo platform.
