first of all, this game really needs you to grind alot for the gems (basc currency to summon) by doing either the story or the events (the first clear/rewards for clearing). the leveling system is pretty easy to understand, good main/support characters aren't impossible to get for a f2p like me.
story wise : its a pretty decent story which I can follow. of course its not so good that i just listen to the dialogue n read the text, not at all HAHA. other than that, its okay
gameplay : hahaha the memories that I get from my countless hours of grinding this game and falling asleep. but for real, sometimes for me, especially in the later parts of the story, i start to get ridiculously bored of fighting. like im too powerful for the enemies and i try to come up with things to accomplish during the battle like getting more sparks, crits or damage. of course, there are other challenges to do but it's not like im that good yet so i don't bother with it. there's more that i like to mention later on.
sound : its very medieval if i were to describe it. somehow i get this sense of nostalgia from it whenever i listen to it.
graphics : for a game like brave Frontier, its pretty good. of course it can improve but for a rpg like this ,its already alright.
others : there's two things that i want to talk about, arena and that one mode that you unlock when reaching lvl 40. arena in a way has alot of ways to 'cheat'. like of course I don't play it that much but still , i rarely lose and win quite alot haha. of course im not saying that its too easy or whatever. it can hard at times but if you have the right characters and all, you can probably succeed in winning 7-9 out of 10 of your matches. next is the mode tht u get upon reaching lvl 40. i admit, its something that i like to do from time to time when i run out of stamina or energy to play the storyline missions but its not really the best mode to play i guess? anyway other than that, its okay.
overall : ah shit, its a pretty good game.
