Gateway to a beautiful, living, unique world.
I don't think I'll ever find a game that is better than Beyond Good and Evil. I have finished it about 6 times over 10 years, I have explored every corner of it and I can't find words to tell how much I love it.
Some people say that it's not that great, because it's old or because it has simple/ripped-off mechanics, but those people don't understand what is this game about. It's more than just another adventure/stealth game. It's a gateway to a beautiful, living, unique world.
There are many games with better graphics or mechanics, but this game has a soul and there are very few games in the world that have that.
I recommend getting this game right now.
Ignore reviews, don't watch the trailer, don't read the description, don't look at screenshots, just get it and play. There's a huge chance that you will fall in love with this game forever.
And it's a chance worth taking.
