This is a crosspost from the Steam Deals thread (it really belongs here, but most of the insanity is over there)
I spent ~1 hour getting started and playing 3 in-game days. I the only reference point to something similar I have is Persona 3 FES.
High School Dreams seems to meet expectations in structure, managing activites and relationships on a Persona 3 like level of limited-time-in-a-day. Where Persona 3 is menu driven, High School dreams works more like many third person RPGs/TPSs (Third Person Socializers, duh ^_~). There are customization options for you room/clothes/hair/accessories/makeup with the intention that you pickup more choices from the mall.
The script is well written and sufficiently varied to suit a "grown-up". There is wit, sarcasm, & humor. So far the game consists of dialogs, walking around talking to people, walking around to find people, places, things, shopping, a running hidden-objects-lite minigame, some other guitar hero-lite mini games. In three in game days, I made some friends, when shopping, found things/places, had a date, had a sleepover.
The voice acting is quite enjoyable. While the graphics won't wow you, they have a bright and consistent look that suits the game. I do suspect they are 1024x768 though. No aliasing annoyances. The music sets the mood during activities.
It has a subtitles option (in well integrated dialog bubbles). I didn't catch anything that wasn't also written, but I can't be 100% sure. (Sometimes minutes can go by watching japanese dramas without realizing the subtitles aren't working.) It is also suitable for one handed play.
Minor Quibbles: The engine seems to have a little bit of random momentary pause (but not stutter). The UI isn't completely obvious (it's good, but a little experimentation is in order). For example you can navigate with keyboard or mouse. I haven't figured how to run using the mouse. The inital load time when starting/loading a game is several attention spans long (20 seconds?).
If you have any interest in
High School Dreams, it's an easy recommend at $1.23 (24 hour sale), and I personally would pick it up at it's normal $5.
