Bah, I seem to have walked into the perfectionism/completionist trap. I catch myself googling all sorts of details in order to maximize the efficiency of how I spend my days, and get the most out of stat boosts/social links. Even googled a single monster type in the first palace to be able to hit its weakness.
I'll probably play this game a second time at some point. I should hold off on the completionism until then.
If you really want to fully complete this game (getting Platinum) you actually have to play this game twice as certain trophies can only be obtained then. As usual with Persona games there is a new game plus, which means you start the second playthrough with things you carried over from the first one (most importantly the personal stats).
For anyone who thinks of picking up this game: Do yourself the favour and play the first time blind without a guide or spoiler. Just enjoy the main story (which is for JRPG really freaking good) and focus on personal stats. That makes the second playthrough far more comfortable as you have more than enough time (it is in that aspect less strict the P4) and the personal stories aside the main plot easily justify a second playthrough.
I love Persona 3 & 4 (both the originals and the new ones) and waited over half a decade for this game. My expectations were sky high and that game exceeded even these. I hoped for a game on the level of P4 Golden and it is even better than it. It is basically a more polished version, which still feels different enoguh due to the different setting and overall themes.
The art can only be described as fantastic, the music is great and the game play smooth (love the added movement in the dungeons) and without grinding even challenging at some points. The cast is diverse and fleshed out.
Overall the game can rightly be described as a master piece, not because it is revoltunary but extremely well made. The best JRPG of the current generation (and unlesss Ni No Kuni II delivers immensively I don´t see this changing), IMO even the best overall RPG (but I normally lean more towards Eastern RPGs). Probably one of the five best games I ever played.
