Kickstarter for The Repopulation closes out, and it's already doubled its funding goal. That prompted an interview with Kickstarter Conversations regarding the game's design principles and its second successful funding run. The development team attributed the success to reasonable financial goals and to setting the bar low and expecting to exceed it rather than setting the bar high and struggling.
The interview also goes into more detail regarding the game's design goals and how progression will work. As stated before, the game is entirely skill-based, with older characters having a wider variety of skills rather than being inherently better. Grouping is meant to be painless and advantageous rather than mandatory so that there's no disincentive to grouping up with other people while taking on content. Take a look at the full interview for more details, and if it sounds like the sort of development you'd like to support, you still have six days to jump in and help fund the game.
