independent developers who created a new subgenre designated "rogue-lite", though the games are also sometimes called "roguelike-likes". Indie developers began to incorporate roguelike elements into genres not normally associated with roguelikes, creating games that would form the basis of this new subgenre. Two of the earliest cited examples of rogue-lites are Strange Adventures in Infinite Space (2002) and its sequel Weird Worlds: Return to Infinite Space (2005) by Digital Eel, both space exploration games that included randomly generated planets and encounters, and permadeath. Digital Eel based their work on the space exploration game Starflight along with roguelikes like NetHack but wanted to provide a shorter experience that would be easier to replay, akin to tabletop beer and pretzels games like Deathmaze and The Sorcerer's Cave that has elements in common with roguelikes. Spelunky (2008), released shortly after the formation of the Berlin Interpretation, is considered to be a major contribution to the growth of indie-developed rogue-lites. Spelunky was developed by Derek Yu, who wanted to take the deep gameplay that is offered by roguelikes and combine it with the ease and pick-up-and-play of a platformer. The result was a platform game incorporating the notion of permadeath in which the player takes an explorer character through randomly-generated caves. The intent was to create "deep" gameplay in which the game could be replayed over and over again, with the randomly generated situations driving the need for the player to develop novel, emergent strategies on the fly. Developer Jason Rohrer stated that Spelunky "totally revamped my thinking about single-player videogame design". The formula and success of both Weird Worlds and Spelunky would influence other developers in creating new rogue-lites. Edmund McMillen, the developer of The Binding of Isaac (2011), and Kenny and Teddy Lee, the co-developers of Rogue Legacy (2012), credit Yu's approach with Spelunky as showing how to distill down the nature of a traditional roguelike to apply it to other gaming genres which they had done for their rogue-lites. Justin Ma and Matthew Davis, the co-developers of FTL: Faster Than Light (2012), credited both Weird Worlds: Return to Infinite Space and Spelunky as part of their influence for FTL. All of these games earned critical praise, and their success has led to a more modern resurgence in rogue-lites since their release. The newfound success in rogue-lites is considered part of a larger trend in those that play both board and computer
