Announced about a week back, the Going Rogue: A Festival of Persistence event is now live on Steam. This event runs from now through May 9th and it includes a focus on roguelikes, roguelites, and everything in between. There are discounts and various video events.
There is a compare and contrast video detailing some of the differences and similarities between roguelike and roguelite. You can find that one below these words. There is also a blog post talking about these same things if you prefer to read.
There is also a very lengthy video showing various roguelikes and roguelites from SirActionSlacks, Uberdanger, and TrentPax. You can see the embed for that below.
