Evaluation

Fish Game launched on October 26, 2023 and has been in sustained, active development ever since. The developer — a small, self-funded team — has established a clear rhythm of both paid DLC releases and large free content updates. On the DLC side, the team shipped six fish/substrate packs between February and September 2025, culminating in the Betta Fish Pack 1 on September 15, 2025. The Plant Variety Pack 1 followed on August 4, 2026, released alongside the latest major free update. On the free update side, the developer shipped their biggest update ever — the Chemistry and Equipment overhaul — on May 15, 2026, introducing full water chemistry simulation, fluid dynamics, and aquarium equipment. Just three weeks later, on August 4, 2026, the team followed up with the Tannins and Botanicals Update, which added botanical pieces, new substrates, and tannin chemistry. A bug fix was posted on August 18, 2026, and an August 1 announcement teased the August 4 update with language ("very, VERY soon") signaling continued active engagement. The Patreon program — established in early 2025 — explicitly gives subscribers a vote on which DLC packs are released next and automatically delivers DLC codes to higher-tier members. This structure is a clear, ongoing commitment to continued content releases driven by community input, with no announced endpoint. No developer communication has indicated the game is winding down or that content development is concluding. The most recent official post was August 18, 2026 — just one week before today's date.
