I finally bought this thru the PS Store and have played about 5 hours of they male's protagonist's story. So far it's been alright. Following are random impressions:
The difficulty, as mentioned, has been non-existent thus far. Even the bosses to this point have died in just a couple rounds of combat. Healing points are usually found in each area that will fill your party up for free. The main menu also lets you use your "Force Points" to restore the party's HP at any time (these points are gained from battles and by breaking items down, and have other uses, as described below)
Grinding isn't really necessary because of this but there is a big crafting system in the game. Enemies drop random parts and objects that can either be broken down for "Force Points" which you use to strengthen your party's main weapons (gain new abilites, make abilities use less "mp" and increase attack) OR these items can be combined to make new weapons and armor. It's always a give and take as to what you want to do with the items and this whole system is BY FAR the most interesting part of the game up to this point.
Dungeons have been maze-like with enemies all on-screen. You can easily avoid most, or sneak up behind them for pre-emptive strike (making the game even easier lol). Scattered treasure chests, dead ends and simple puzzles are the order of the day. Graphics are OK, nothing amazing but they are simple and clean (oh no I didn't).
Music is mostly forgettable. This is usually one of my favorite aspects of any game and I'd give it average at best. I haven't found myself humming any tunes when not playing the game, or even remembering any of it. It isn't grating by any means, but totally average.
The equipment system is a little odd. Each character can equip up to 4 weapons. There are 2 types of weapons. The first consume RP (magic points basically) when you use skills associated with it. The second uses Durability and each of these has a DUR rating. When that reaches 0 you can't use the weapon in battle anymore, but you CAN use it in crafting.
I know I am early in the game but I haven't found many "towns" yet. Or maybe it's that they are not really traditional ones. There are npc's to talk to and chests scattered about but no shops or anything like that. Granted I am early in the game and this may change. With how the crafting system is set up, though, there may not even be any kind of shops in the game. You can craft what seems to be things for every slot you have so....I would consider these half-towns as there isn't much to do in them other than talk to a few people then move on.
Oh yeah, battles, they are easy but also fast so you never feel that bothered by them. Tapping R lets you zoom through it and 99% of the time I do this and just have everyone use their default attack to quickly kill everything.
Story so far is average as well. I can't say much about it as I'm not horribly far yet but it has been decent. Just like the music, it doesn't stand out at all right now.
World map is a map you choose your destination on then it takes you to that area. It is serviceable, nothing more.
Overall I would say that I am enjoying the game and I will keep playing. The whole Force Point system used to strengthen your weapons combined with the equipment crafting makes for a really enjoyable sub-system that keeps me coming back for more. If these kinds of things sound like fun to you, I'd wager you will enjoy your time with this game.
