PLOT: It's nothing super unique, but the writing really makes it work quite well! Basically, the men of Valencia have all vanished, likely due to the machinations of an evil goddess, and you are the saviour tasked with restoring balance (in a harem situation of a village where you're the only dude left!). Different character arcs really do feel different and unique in their own right, and it's well worth the effort of running around performing various quests and trying to get to see everything. The overarching "main" story is also very interesting to follow and it's one of those few instances where the plot complements the sex scenes nicely.
ART: Artwork can be a hit or miss for some people. Personally, I quite liked the voluptuous 2D style, and the almost cartoonish colour schemes, but I can see why the faces or the artstyle may put certain people off. The scenes are a mix of 2D stills and animated 2D, and it really works quite well! However, the assets are generic RPG Maker maps, and the sprites are as well, so nothing special going on there.
WRITING: Writing is really quite excellent! Characters are lovable and believable, with their rising levels of lust are portrayed nicely. Writing of descriptions, dialogues, and the quests/storylines are all well above average. Commendable!
GAMEPLAY: There's basically no combat here, which is fantastic, as I've been through too many grindest RPG Maker projects already. Objectives are mainly exploration, with heavy emphasis on puzzles, that have to be solved in order to progress anywhere. The gameplay isn't too difficult, and the puzzles make you work just the right amount for the rewarding scenes at the end.
SOUND: Standard RPG Maker soundtrack, with a bit of stock moaning and sex sounds thrown in; these aren't really used all that well., however, and I could really do without. They sound subpar and feel artificially forced in. A low point in an otherwise great game.
Overall, I'd give this game a 9/10! The only reason I didn't give a full score is because the soundtrack, maps, and sprites are all nothing special. That being said, they're sufficient, and do the job. Town of Passion really stands out as one of my favourite adult games out there, and it's already got plenty of content, and is definitely well worth playing.
