Learning from Game Reveal
We are extremely thankful to everyone for the feedback and support at our Steam Page launch! 🙏 From what we learnt, we decided to take our game in the direction that is: More battlefield TBS focused — learning from Advance Wars, Wargroove, Into the Breach that Steam player loves. Less historical 4X focused — not trying to be a full-on Civilization, but extending the TBS genre by learning from Polytopia. Important features* Satisfying combat / combos game feel Great replayable small map campaigns (non-dragging) Exciting gameplay progressions / upgrades for Roguelite Fun AI More platforms & cross-platform support Multiplayer + Online multiplayer matching Mods support Map editor (?)*TBC after play testing at demo Will not do Deep city building / economy Tech trees Layering more systems (diplomacy, religion etc.) Giant map sizes for epic empires So don't worry the game is definitely in active development, but please do expect changes and upgrades to the direction vs what is currently on the Steam page! For more real-time discussions and updates, check out our Discord. We'll keep you posted. See you around! 🤘 Ahsaurus team Yes, in hindsight our game does feel more like a classic charming battlefield TBS than 4X… but hey, we're human, not dino. 😅Read full article on Community Announcements (fossilpunkteam)
