Fantasia: The Realm of Thanos & Fantasia: Requiem of the Abyss (sequel)

I'm a fantasy fan, so I personally really enjoyed these games. If you're not into the whole fantasy storyline though, I don't think the mediocre drawings are going to be enough to hold your attention. There's a third (and final, according to the creator) installment in progress.
Actually, I accidentally played the sequel (Requiem of the Abyss) first. This was probably a good thing though, because the first game's plot wasn't particularly enthralling (but a very good attempt for the creator's first time making an otome game).

The first game revolves around a female protagonist who you can name yourself, whose goal is to make the Demon King fall in love with her before the end of the game so he doesn't destroy the world. It's available for free download here: http://renai.us/game/fantasia_realm_of_thanos.shtml

The sequel, Fantasia: Requiem of the Abyss, revolves around the children of the main characters from the first game, and is much harder to get a good ending with. It's available for free download here: http://renai.us/game/fantasia_requiem_of_the_abyss.shtml . The walkthrough (much needed, in my case, but try the game without at first) can be found here: http://hanakoforum.nfshost.com/phpBB2/viewtopic.php?p=4884.
