No genre in any media will ever be "dead" as long as there is someone somewhere indie or not that actually cares enough in order to put some actual effort into what they are making. There will always be those that don't give a rat's ass about what they are making and are just looking for a paycheck, thus half assing everything and copy pasting whatever worked with the last guy that actually tried, but in the end there will also always be those who actually have the motivation and ability to innovate where everybody else is just lazying out, and that's where games like this come from.
