well i know the number of people that gives a fuck about this game here are between -1 and 0 but writing pointless impressions of game nobody plays is what i do...
so where to begins,this game is wordy,like metroid other m pointless wordy... if you played the actual novel thing (basicaly if you are called viz or you are me i guess) it's really not that far from it,the intro alone takes like 30 minutes full of monologue and pointless rambling,tough it settles to normal level when the actual game kicks in
the combat is at least original,basicaly each combat turn you and the enemy have to pick 6 action between attack,break or guard,it's basicaly rock/paper/scissor... attack beats break,break beat guard and guard beat attack,the thing is that each enemy follows a determinate pattern so for example there are defensive enemies that spend most of their action picking guard or there is a beast like enemy that always pick 2 of each actions in a A-B-C-A-B-C pattern
the game also tells you out straight 1 or 2 of their actions,so for example the game might tell you that the beast enemy is using his first action to attack,knowing this you can assume his 4th action will also be used to attack and that his 2nd and 3rd (5th and 6th) action will be either guarding-breaking or breaking-guarding and therefore act accordingly
the plot... each character gets the aid of an historical figure with super powers called servant and they have to beat each other with it until THERE CAN BE ONLY ONE,the game is divided in week and in each week you are supposed to play detective and gets more info on your opponent so you can learn about their life as an historic figure and therefore learning their special attacks and stuff... the more you learn,the more the game tells you about their action when the time for the boss fight come's around
the dungeon itself are super-bland affairs of futuristic looking cube's,the interface looks really similiar to persona 3 up to your servant making quips after every battle and going "LEVEL APPU!" but other than that there is no similiarity with persona at all and uh... that's pretty much all i have to say about it
it's not terribad but it's also totaly skippable if you don't give a fuck about the source material in the first place
here's a review which i think sums it pretty nice
