i've been playing VP: Plume. tbh, it's story is tl;dr and boring (to me) and its battling is extremely difficult if you want maximum rewards from every battle (which, naturally, i do) while keeping the option of getting the good ending. for what its worth, the story is heavy-handed and does exude a sense of maturity, although (much like FE), a lot of the gravity of it is taken away when its just 2D images talking to each other on a screen.
still, it's enjoyable. it actually encourages strategic thinking, unlike a lot of other srpgs. while the maps are isometric in design, actual battling is the same as any other VP game (4 characters mapped to 4 buttons, a special gauge, etc). its definitely worth checking out if you're a fan of the series. my only REAL complaint so far is that, 5 hours in, i have yet to see a Valkyrie!!
