Picked up Brave Dungeon/Dark Witch Story earlier today. Haven't tried Dark Witch Story. so I can't say anything about that.
Brave Dungeon is a dungeon RPG. There are 5 dungeons and you can play whichever you want. They are unlocked from the start. Of course, if you pick the later dungeons, you won't be strong enough to succeed but it's nice you can switch between them.
Each dungeon had a certain number of floors. Not sure how many but I'm currently in floor 3 of the first dungeon. The maps for each floor are not complicated at all. Very basic. You have visible enemies as well as the boss and you run into them to start a battle. You have treasures to find, which are materials to make accessories. Theres a % in the corner that will show how much of the floor you've uncovered.
When you first enter a dungeon, you can't run away from any battles. It's only when you uncover 100% of the floor that you can.
When you 100% a floor, you'll get an icon to represent this.
Battles are turn based. You have a team of 3. One that is your main and you can choose the other 2 from a selection of 7. You can switch to new characters whenever you are back in town.
The only equipment you have are accessories, that you can find during a dungeon or you can craft them. No weapons or armor. Certain materials are in certain dungeons, but you can look at the material book to see which is where. In the beginning, you can equip 2 accessories but you should be able to unlock more as the game progresses.
You can also create other material. When you have the required items, the new material will be highlighted to let you know it can be created.
There's a bestiary which shows enemy stats and what materials they have.
When you level up, only your HP and SP(?) increases. If you want to increase the other stats (which there are 4) you have to use the currency, Tres. It's gained after every battle. If you want more attack, spend 500 Tres to increase it by 1. If you want to increase it again, it costs 1000. As far as I know, you only get +1 every time you do this, but the amount of Tres you need increases by 500.
Magic Items are what you use during battle. Your potions and whatnot. These need to be purchased with Tres. A potion might cost 500 for one but if you want another, it'll be 1000. Like stats, the amount of Tres will also increase. These items get replenished every time you go back to town. Free of charge. Same with your HP.
Every 10 levels you can change your class. You have 2 options and each give you a different skill. Not only that but one choice might increase your attack by 10 and your defense by 5 OR the other choice might switch it around and increase attack by 5 and defense by 10.
There are material requests (3 at a time), where you bring the required materials and you get Tres and a Lunch Coin in exchange. Lunch coins are used to give a random team member a random stat increase, depending on what shows up on this basic roulette system.
The game defaults the difficulty to Expert, which I think is the way to go. The other 2 are Easy and Casual. You will have some trouble with bosses or when you enter a new floor but that can be solved with some grinding of levels and Tres (or stat increase). Accessories can play a big part as well. Equipping someone with 2 attack up items can make a difference.
I find the game simplistic but addictive because of it. I can see it being repetitive but it hasn't hit me yet. I'm currently on floor 3 of Dungeon 1, with a party who is in the 20's.
It's also on the 3DS. Not sure if there are any differences in gameplay.
