I have played a lot of Hackroms and randomlockes. Crystal clear it's one of the best in my opinion. It's really polished. The difficulty it's just a little bit above original games (foe pokemon have a better move set in general and they keep up in levels). The story it's not a masterpiece but it's good enough. And it's complete, something that a lot of hackroms can´t say.

There are a lot of pokemon in the world if you want to play randomlocke.

The new elite 4 and others makes it a very complete pokemon experience.

Maybe it lacks in produced cutscenes, and it still doesn´t have post game but that aside this game is a way better experience than the official ones by gamefreak to be honest.
