A TCG with some potential, but which is ultimately upsetting. Don't spend any money on it.
The first thing it's missing is the ability to trade cards or other items with other players. The ability is simply not available. What this means is that the only cards you can ever have are the ones that you get through playing the game. Each card has a rarity associated with it that tells you how high it can be leveled, and approximately how powerful the card is in relation to the others. The rarity is conveyed with 1 through 5 stars, and in the roughly 9 months of playing I've done before writing this review, I've obtained exactly one of the 5 star cards. And the only way I managed it was by spending a fair amount of money (a hundred or so dollars) on items to recover energy so I could keep going through an event they offered for a short time.
There are ways to summon cards as well... and you have a shot (at least they claim you have a shot) at summoning good cards. But again... you have to spend money. There's a summoning type that they call a "bell summon" which is a list of 80 cards. Each summon gets you one of the cards, and costs 980 of the in-game "gold". The in-game gold costs $12 per 1000. Within the list of 80 cards is one good card, and it claims you have an even chance of getting it on each summon. I spent approximately $250 trying to get a card I liked, and didn't get it. That was roughly 20 draws from the deck. It was at that point that I realized I was doing something stupid. That amount of money is ridiculous for a single card in a game. If you end up needing to draw all 80 cards from the deck just to get this one good card, it would cost about $940. And yes... the other cards are just normal cards you can get from normal game play. Those normal game play cards are pretty lousy compared to the special cards you can get if you spend hundreds of dollars.
The game is set up such that if you want to do well in the game, you must spend real money, and a lot of it. I understand games wanting to get some money by offering special things to players for money... but the balance in Ayakashi Ghost Guild is way off.
The cards are attractively drawn, and the story is nice enough that it might be entertaining to play through. Just make sure you have will power to not spend any money on the game. It's not worth it.
