Note written 2026-08-27; the live figures above take precedence over any numbers in it.

A 2D physics-based rocket-building sandbox where players design and launch spacecraft to explore a procedural solar system.

Spaceflight Simulator holds a quiet but genuinely engaged community (97% positive sentiment, 75% still playing) with solid mid-four-figure monthly residuals and a lifetime floor of roughly 300k units. The early-access label and single-developer studio status create acquisition appeal for a publisher seeking a stable, complete catalog title with minimal maintenance overhead; the modding infrastructure and cross-platform pedigree (mobile origin, now Steam) suggest revival or console-porting upside. Risk lies in the narrow genre niche and lack of localization beyond English, which caps growth ceiling. Most realistic play: acquisition.

• Risk: Narrow appeal: players compare it favorably to Kerbal Space Program but explicitly note it as the easier, simpler alternative, limiting addressable market to less hardcore audiences.
• Risk: Early-access flag persists despite 2-year lifecycle and apparent feature completeness, signaling either ongoing development friction or a developer choice that may confuse buyers about true product status.
• Risk: Single-studio, single-title publisher (Team Curiosity) carries key-person risk; no post or update in the last 4-5 months despite active residual revenue.
