Ok I don't want to fanboy over this game but be warned this is going to be very bias
Ok now lets put it bluntly, I love this game, when I first played this game back on the PS3 I fell in love with it instantly, how it looks, the characters, the music, the gameplay I loved ALL of it so without spoiling too much about the game I'll explain the plot.
The year is 1935 in a ficitional land called Europa, and yes it is essentially just Europe and basically, their WW2 happens with the Empire (Who are basically the Axis) and the Federation (who are basically the Allies) trying to out kill each other, during this though the Empire decides to attack a small neutral country called Galia and this is where you start the game.
You play Welking Gunther, the son of a EW1 (their WW1) Hero coming home to help your sister and maid evacuate, on the way Welkin gets arrested by the town watch due to being a suspected spy where he meets one of the other main characters, Alicia Melciott, shortly after your attacked by an empire scouting party and the game begins
now from that description your probitly thinking a very 'Tales of' game but in actuallity the game has alot of things similer to the XCOM line of games, the game is a mixture of real time and turn based gameplay, to put it simple your turn starts with you on a birds eye view with icons repsenting your troops, you select one and assume direct control of said character, here the game unfreezes and you can be shot at, you then move around, crouch behind sandbags and more but you have a bar which dictates how far you move, outside of that you can end or turn or enter aim mode.
here all gameplay stops again, the enemies shooting at you finish (though the mounted guns tend to misbehave and keep fireing for much longer) and you can do a more aggresive action, haling, repearing or the more obvious one, shooting the opponent, but be carful because if your in range of the enemy and they survive your attack they're allowed to counter attack, then you can only end your turn, when you run out of command points you end your turn and then the enemy's begin, basically being able to do the same thing.
Theres also permadeath in this game, baring a few missions every mission has one possible failure state: Welkin Dies. if his tank explodes or on the few missions he's on foot he hits 0 health you instantly fail, outside of Welkin there are 4 more "Essential" characters, these will never die in battle and will instead retreat, being unable to be used for the remainder of the battle, then theres everybody else, if they are killed then they stay dead, no "Amazingly they survived" or retirering due to injurys, when they die they are perminatly dead till you play through the game again.
next is the story, as you would expect for most japanesise games (Not all, just most) the game has some very cliche anime-like moments and archtypes (Including an obligatory beach scene) but actually keeps itself very down to earth and showcases something in war that most war games don't manage, how in war a situation can go from silly and fun to dark and depressing in the blink of an eye, this allows the characters to feel like actual people, you feel then reacting to the sudden changes as you would and that in turn helps you to attach to them.
Now incase i go over the character limit i'm just going to randomly throw the 3 problems I have with the game so
1. The difficulty is all over the place, some missions are rather difficulty then suddenly you get an easy one, theres one mission that is absurdly difficult about 1/3rd of the way through the game but the next 4 or 5 are a cake walk, theres no real curve which makes the experiance a litting jaring
2. the AI sometimes goes into full derp mode, I've had snipers run point blank range into my shocktroopers to try and snipe one, I've even had AIs just end their turn standing in the middle of the battlefield because they got shot once
3. the ports animated cutscenes are at 30fps 720p but the game can be played at 4k and 60fps, small gripe but a little jaring, the game looks beutiful anyway
ok still not at the character limit? good I'll continue
one thing that strikes me about the game (outside of its graphics which look beutiful especially in the animated cutscenes) is the music, which was composed by Hitoshi Sakimoto who you may know from his work in FF12 and the Tactics series, the music uses alot of violins and piano work to help express the emotion being felt at the time including tension, joy and sadness, of course this runs into the problem though that alot of tracks are repeated but thankfully it doesn't get too annoying to listen to after multiple playthroughs and it tends to save the best tracks for when its needed
now to finish off is graphics, and i'm just going to say this now, SEGA needs to use this game engine more, while it does defently have rather low texture quality its only noticeable at really close range, the Canvis engine has that really great combination of vibrant colours, strong lighting (when it's used which unfortunatly is not often) and makes the characters have very distinquishable sillouetes which prevent you from being killed cheaply, there ARE a few issues with the physics but the game doesn't use then in say how a Call of duty game uses it, typically its saved for the ragdolls which disappear after a short while
Overall Valkyria chronicles is as good now as it is then, it is well made and is one of the best games of its generation and mayhaps even be with in a few "best games of all time" list. I would defently recommend buying this game.
