Most of them cost money (on dlsite, steam and a lot more), but this is a pirate forum so you can get games and unoficial translations for free (anyway, if you enjoyed a game and can afford it you should buy them to support the devs)
About if they worth it or not, it depends each person, i prefer spend 5-10 euros on a good hgame where i spend a lot of hours than a new CoD that costs around 70 and i get bored very soon
