✦ AI summary

Ratropolis is a hybrid deckbuilding, citybuilder, and tower defence game that players find addictive in concept but frustratingly flawed in execution. The primary complaints center on heavy reliance on RNG that often works against the player, unbalanced cards and hero powers, clunky unit movement, and too many decisions happening too quickly without meaningful pause functionality, which strips away player agency and makes planning difficult.

I had to pull the plug on Ratropolis because its overtuned difficulty completely strips away player agency. Calling it a card game is almost a misnomer—you can't craft a coherent build when the RNG gods relentlessly deal you garbage hands during low-stage runs. Wasting all your assets on early waves with zero hope of survival isn't a rewarding challenge; it's a flawed loop that punishes you for things completely out of your control.

Fun little deckbuilding/citybuilder/tower defence game very tightly balanced, had fun getting 100% but a few achievements were ball breaking.

i actually enjoy this game, but i have to down vote it for multiple reason: unpolish gameplay: the card are not balance( some card are completly useless or so specific like the card that allow you to remove curse on enemy for money... ) the hero power are not on the same scale, a lot is left to pure rng, but the rng is not in your favor the unit movement are clunky and slow you almost can never react to a emergency (1 frenzy rat who manage to sneak the last wall on the 3rd wave will destroy your palace in only 2 hit) the citizen resource is brutal, if your commander doesn't allow you to increase it (only a few can), you need to find a way to increase it periodically or you cannot sustain a proper army or using labor, with no guarantee to ever find any some boss have too strong ability: one just sleep your whole melee army then kill them 1 by 1 there is no story, there just not enough space to build even when expanding relentlessly expecially for builder. regarless, the game is still quite fun to play, but you have to play a lot to become good https://store.steampowered.com/app/1108370/Ratropolis/#enough to enjoy it, and even if you play perfectly you can easily reach…

Not a very good game. The idea of mixing the Kingdom series with a deckbuilding game isn’t bad. In theory, it could actually work, but the implementation is quite bad. The game is cheap, and this is absolutely my type of game, but even then, I just didn’t find it very fun. The three “maps” are barely different from each other. There are a bunch of different main characters, each with their own special cards and abilities and that's a plus. There are way too many decisions to make in way too little time, and you constantly have to stop and read what each card does. On top of that, there are plenty of cards that generate new, random cards, which makes things even more chaotic. The game doesn’t actually pause while you’re reading cards it only slows down. And when you hold a card to read it, it becomes much smaller because of the card-holding animation, which makes the whole thing incredibly frustrating. The game isn't complete trash though. I'd give it a solid 4/10

The Planet Coaster DLC catalogue closed in 2019, so there is no curve left to wait out. Our record shows the collection bundle costs far more than assembling the same packs one by one.
