Very enjoyable, with a decent selection of play modes. The varying sets of cards available in the market provide a good amount of variety between games, and online play has worked well. The English translation has a number of errors, but nothing that interferes with understanding the game. My only major complaint is that the pace of online play can be a bit slow for my preference.
Recently got into this game because I was bored and had some money to spare, I love it. I normally never cared for card games, but how it's like Dominion its so damn fun. I tried phase 1 from 2017 before coming over to this new release, love all of it. Also, Cute & Funny Princesses ToT Also, i think the min specs to recommended specs are botched. I'm on a Surface Pro 4, Linux Mint XFCE, i5-6300u, 8GB Ram, and a Intel HD 520, it runs so damn fine. I'm so happy it does to.
I love this game, I have 2 sets of the physical version of this game. Fairy Garden with expansions (Path Before Heaven and Six City Alliance), also the 2nd edition. I play it a lot with my friends. The steam version is a little bit expensive for us in Indonesia, but i would say it's worth the price (on sale lol). The single player content is pretty good, there are stories for each princesses which I really look forward to. it builds on from the 2nd edition. The cards..... are very powerful and the game can finish very quickly. although this might turn off some players, i'm personally okay with it, as long as i'm playing bots or strangers online. with my friends? thankfully we can customize our own deck to use with friends. game definitely need some polish and bug fixes. and the missing voice lines too... but i guess that's another case considering voice actors are expensive......
Great implementation of the game with new mechanics. I mostly played the card game in real life but the way that the Princess abilities and some of the cards have been reimagined feel very fun and balanced. I especially appreciate the solo mode campaigns that give you evolving decks and a character specific card to help understand how to synergize with your princess. This is my new rotting in bed with a Steam Deck game.
