The Phoenix Project, and a recent interview with the team behind Missing Worlds Media talks about what it's like to try making a new game after the closure of City of Heroes. And one of the game's core design principles has come about precisely because of that closure, because the team wants to make sure that even if the game isn't a major hit it can keep running in maintenance mode.
Kickstarter is not the last chance for the project, as the team has no plans to shelve it if funding goals are not met, but no outside sources have been approached yet. The interview also stresses that the game is not meant to simply be a clone of City of Heroes, with a development focus on including the best parts of the game rather than simply copying everything. For a deeper look behind the scenes, read through the full interview.
