IMO RogueBasin should cover every notable roguelike and roguelike-like. If anyone sees a notable game (or simply their own game) which is not on RogueBasin: please add it! As side benefits, this will automatically add the game to
IRLDb, eliminate all controversy regarding ROTY inclusion, and make it more visible.
For example, FTL definitely should be added to RogueBasin.
Then, ROTY should use RogueBasin and ADR as a source of information, as usual.
I am not sure about Spelunky HTML5... just a port IMO.
Why is HyperRogue III controversial? It
appears on RogueBasin (although the page is named "Hyperbolic Rogue"), and on ADR (although with some errors).
Edit: are you looking at the RogueBasin news, or add all
games on RogueBasin with a recent update? (I am for the second option, although there is some wrong data there)
