ZONE games aren't really games, but sweet Jesus does 4chan love them and each one is well-made. Another Illusion game, so it's good stuff as usual.
It creates some funny and enjoyable scenarios and some sweet 3D hentai scenes; it's actually pretty complex (and over 6gb). A sequel of this game known as Artificial Academy 2 was released on 2014. Artificial Girl 2 and 3 (also called Jinkō Shōjo 2 / 3), are two "3D erotic life simulation games" where you play as a young male on a island full of girls. A not-turn-based RPG hentai game with a good plot and enjoyable kill everything game play.
Probably the most serious game ever done with RPG Maker XP, because it's heavily scripted and the graphics are really professional. You are a yakuza member that just recently got released from jail.
Different artists worked on the visual art, so they're not all so awesome; not like a leech-girl could look better anyway.
There is also a worthy sequel, and the finale released.
There are multiple dungeon themes and over 10 big dungeons to beat.
If you choose not to use your potions, you can choose to "life steal" the weak downed enemies, not to mention finish off the bosses.
Similar to The Legend of Zelda by dungeon and sword-play.
Contains dungeons filled with enemies, secret rooms, weapon upgrades, and bosses.
You play it like an old first-person dungeon explorer, only with random naked chicks to play with.
The sequel is more of the same, with a more convenient map and animations in some scenes. There's a limit to how long you can maintain the pocket world that serves as your hunting grounds, and losing fights or letting your girls escape depletes it.
It should be noted that as of now, many foreign countries have been IP blocked and none of the online functions will work at all.
