ArtDink is pitching A-Train 9 PRIME LINE as a rebuild of the series' construction tools, with track building and road laying both overhauled for freer city design. The buildings revealed alongside the campaign fit that pitch: small-scale condominiums, under-elevated storefronts, surface parking lots, and small shrines, all sized for plots under 40m by 40m. Parked vehicles, monuments, flower beds, and hedges can be placed overlapping within building grounds, which allows finer work around station fronts and landmarks. A feature video is out, and the campaign period and purchase method are on the special site.
