I can add stats once we get a stats template going (I don't know how to code so I can't do this part), but not strategies. The thing is, in-game it only shows the Shadow's HP, Attack, Defense, Skills, elemental resistances, and drop items.
Parameters like St, Ma, En, etc. and ailment resistance can only be found out through datamining, which from a quick google search no one has done yet.
Exp isn't listed but it's possible to find it out via simple math.
I doubt they'll move from the high school formula since that's what sells. Atlus back then wasn't against experimenting with new ideas as we've seen with Eternal Punishment, the themes in Nocturne, various spin offs like Digital Devil Saga and Raidou, etc. Lately they are going the safe route as some interviews regarding P5 point out like "feeling right at home" with the game and that, personally, held P5 a bit.
While a new writer can bring the possibility of experimenting new things I wouldn't be surprised if they went with the same formula and standards (which personally I don't like) ever since P4.
...What do you mean first Persona game? As in the first ever made? Then that would be Revelations Persona which is a badly localized one, then there's the PSP port Shin Megami Tensei: Persona, which is arguably better.
You can also call it Persona 1... shocking, I know.
