You're definitely allowed to have the opinion that you don't like the game but some of the things said were a bit strange.
For example- it has been said you can Catch 'em All by the end of episode 19 (the final episode) this means that all of the nerfed pokemon will be available by the end of the game. Earlier players have some pokemon available to them that were called too powerful and either moved or nerfed (for now). This was all to keep the integral challenge of the game.
You also seem to be saying that because this is quite different from the standard pokemon mold it isn't pokemon and more like Final Fantasy or something. It is still a pokemon game. You catch and battle with pokemon challenging gyms. It is very much a pokemon game.
There is also no need to compare this to another game. They are different games and people will have opinions on what which one is better but Ame and whoever made liquid crystal wouldn't want people to be comparing their games as the aren't competing. There is space for more than one good pokemon game in the world so there is no need to say it could never compare to the one you like more.
Also saying the game asks you to cheat is somewhat ridiculous. The game is hard and asks you to think about strategy towards leaders but it in no way asks you to cheat. Cheating is an easy way out of the challenge the game poses.
So overall, no-one is stopping you from deleting the game. If you don't enjoy it you shouldn't play it. But why you are bashing up a game that so many of us enjoy for being unconventional and difficult bemuses me.
