Eushully games are one of the rare varieties of Hentai games that actually invests heavily in an interesting, challenging gameplay experience in addition to multiple romance options. For me, this is hella fun. But the game still does have some workarounds for your type anyway: not only is there an auto-battle button (there's a lot of trash mob decks wandering around, so most players will make use of this anyway), but there's also a dungeon (part of the first 'append disk') available starting at chapter one, Hetares Dungeon, that gives you a bunch of cheaty items if you run it. The game kinda scolds you for using it, but it only makes the combat easier without changing the story/available scenes.
Gameplay-wise, it's part a strategy game and part an RPG-inflected card battle game. Strategy I can generally get behind, but while I usually don't get into card games, I think this particular card game style is actually quite fun to play. Your hero card is one of your party members as the 'leader,' with a larger health pool, generally more attack points and special abilities, who stands in for the player's overall health pool. You also summon other monsters/items/party member representative cards to fight for you, as your deck and playing field allows. You try to deplete your opponent's leader's health to defeat them (usually; sometimes other gameplay conditions apply), and they try to do the same to you to defeat you. You level up your party through combat, collect cards, apply equip cards to get RPG-like bonuses, etc. I have really been enjoying it, but it definitely requires the concentration of an actual game rather than the mindless clicking of your usual hentai fare. Expect to build decks, make strategic choices, and get your ass handed to you sometimes even if you ARE paying attention. Also, not all monsters are beatable the first time around. If you want to see all the content, expect SEVERAL replays.
Story-wise, Eushully games tend to be fairly boilerplate stuff. Usually it's a monster-filled swords n' sorcery fantasy world of some kind, but in this case it's more of a supernatural otherworld high school story. It feels super dumb to write that that's ordinary, but I'm not generally an anime guy so I just know that's a very common setting for Japanese fiction. Expect a whole bunch of quirky high school ladies all in love with the main character, including his little sister (yup, it's an incest game! Again, I love that Eushully does incest stuff, YMMV), there's corporate intrigue, and a devils-vs-angels-vs-humans storyline that's kinda Shin Megami Tensei-style. Still, it's generally well-written and interesting enough.
Art-wise, this game looks great. Not just the hentai (yes, it's got mosaic censorship), which is of course a major emphasis of the game; but also the regular characters, items, and story graphics. There isn't a huge variety to the female characters (do you like your white teens in busty or non-busty form? What's your favorite anime hair color?), but again: lots of choices Eushully makes are traditional hentai stuff, albeit with much more depth and care than most companies put in.
All told, this is a great game and we're lucky it finally got a full translation. Considering how cumbersome this is to play with a text hooker, this version is SO much more user-friendly in English now. I'd say that, if you enjoy hentai at all and wished there was just more gameplay in your hentai games, this should be an instant download. Five stars, no question.
