What are some must play hacks that have difficulty or cool features to them? Preferably maybe every pokemon up to Gen VIII? I'm only asking because while I scour /vp/, check that dogshit site Pokecommunity and even fucking reddit somewhat frequently, shit like Blazing Emerald, Radical Red, Unbound etc went under my nose and I only found out about them weeks after they were released by seeing anons discuss them in random threads.
Also general romhack discussion and recommendation thread so people don't shit up the development general.
