Dinsun Review
Look, I’ve seen plenty of mobile simulators that try to pass off arcade physics as 'realism,' but Hmmsim 2 is a different beast—and not always in a good way. Dinsun here, and I have to say, the technical foundation is solid. The recreation of the Seoul Subway lines is clean, and the BVE Add-On support is the only reason this game remains relevant. It’s a niche within a niche. You aren't here for flashy UI or 'fun' in the traditional sense; you’re here to stare at a speedometer and hit your marks at the platform. The addition of an outer view is a welcome bone thrown to the casuals, but it doesn't mask the fact that the base game is quite lean.
However, we need to talk about the 'game' part of this simulation. Once you’ve mastered the two included lines, you’re left with a file management simulator trying to get BVE routes to work on a mobile OS, which is a headache most won't want to deal with. The graphics are sharp for a 2015 release, but the world feels sterile—frozen in time. It lacks the 'living world' feel of modern PC counterparts. It’s a serious tool for serious people, but as a product, it feels more like a legacy port than a finished journey. It’s competent, yes, but it lacks the soul to earn a high recommendation from me.
