It doesn’t shy away from asking important questions . 
It is highly educational.
It has well-written dialogs.
And it’s as incomprehensible as Metal Gear Solid 2.
You might have guessed it - it’s a Pokémon bootleg, one that’s usually known as Pokémon Vietnamese Crystal. And it is probably the most entertaining video game I ever encountered, thanks to its weird, dadaist charme. Some things are barely comprehensible, some are just plain wrong, there are about five hundred items called “POLE”, about 50% of the attacks are completely misnamed (“FLAME”? It’s Water Gun, what did you think!), but every second line in the game will make you laugh so hard it hurts. There are a couple of Let’s Plays of the thing, the most famous one was done by Delicious Cinnamon, who also have some other Pokémon bootleg games in their library. You should totally go watch it right now.
It’s simply my favourite video game ever, and it was created only by accident (automatic translation, probably).
