About Once Upon a Galaxy

Once Upon a Galaxy is a fast-paced, free-to-play card battler of cosmic proportions. Captain a crew of characters from myth and fairytale lore into battle across a spectacular galaxy in search of allies, spells, and treasures to ensure your ultimate victory!Begin each game by selecting a Captain with its own unique effect.Will you choose Dorothy to help complete her friends’ quests? Or Dragonmother to discover what hatches from her Mysterious Egg? Play as Indiana Clones to "clone" your best three treasures, or lead a troupe of toys as Geppetto!More captains are released each month, so there’s always something new to try!Galaxy features an eclectic cast to help you on your journey. Recruit characters and cast spells each round to prepare for your next challenge. Carefully position your cards while planning your turn—then enjoy their auto-battle against other captains and crews!Upgrade your crew throughout the game. Character-copies give bonuses and discover powerful treasures. Enhance your board directly to keep buffs as you replace characters. The most powerful cards appear later in the game—find a Legendary crew to help make you the last captain standing!You can capably lead any odd character, but your most powerful crews will come from smartly-selected synergies. Combine treasure effects with characters’ abilities for powerful outcomes. Leverage powerful character factions, each with their own focus, such as treasure-loving Dragons, spell-enhanced Mages, or Toys which summon additional characters during the fight!In addition to the common pool of cards you encounter each game, each captain commands its own list of collectible elite characters to customize your plans. Select 12 cards before the game—they’ll be mixed into your card pool to potentially draw!No timers, no pressure. Galaxy's matchmaking and async-multiplayer mean you can battle fun-but-challenging opponents whenever you want. Face real boards from other human players’ earlier games. Your finished run will join the opponent pool for others to challenge. It's fast, strategic, and endlessly fun!When you're ready to crank up the intensity, you can play with friends in 6-player live lobbies... warning: live lobbies are the ultimate competitive experience!While our Steam build is great for the desktop experience, Galaxy is also available on your phone or tablet!

I used to love this game. The whimsical card design and the asynchronous battles have been a major selling point for me. It felt fun and refreshing and you certainly did not need to spend any money to be competitive. This made any pass purchase feel like you were supporting the dev team for a job well done. Unfortunately, the game is now at a state where multiple captains are dumped in the game every month, making this increasingly daunting for new players. As the, inevitably, imbalanced captain pool grows, f2p players will be stuck with considerably worse captains or a vastly diluted card pool, meaning their chances of winning diminish with every passing month. Worst of all though, and the reason why I am uninstalling, is because the dev team has introduced P2W elements in the shop in the form of reroll. This is an incremental benefit, as the captain pool is ever-expanding, but those who do not purchase the reroll system (which is per card set) are immediately worse off. I wish the game stayed more f2p friendly and less predatory, but unfortunately the trajectory the game has taken means this will only cater to whales. And there are more established card games for whales…

They're adding a permanent reroll button ( that you have to pay for ) in order for you to cycle through your set of 3 hero. Don't have to say more than this, get this game out of here

Another excellent f2p game ruined by monetization that crosses the very clearly defined "P2W" line. Don't waste your money supporting devs that are clearly signaling they prefer a quick buck over long term game health and audience relationships.

Newest change is just the nail in the coffin of this game being worth playing, should be quite clear that this is a bad decision to anyone that really thinks about it at all, I don't understand how a change like this could even get past the idea stage.

Sadly going greedy with p2w element.

Absolutely great game ruined by introduction of poorly designed pay to win features.
