No A working SimCity 4 re-implementation requires reverse engineering proprietary binary file formats and simulation logic, plus a large body of game engine and urban simulation work. Vibe coding can help with pieces but not replace years of specialized effort.
What it would actually take: Requires reverse engineering the DBPF archive formats, the RUL/CTY/SC4 file structures, and the original simulation rules, and then building a rendering engine and simulation core in C++ or similar. Deep game-engine, reverse-engineering, and city-simulation expertise, plus many contributors over a long period, are needed.
