The RET Type R-SG3, yet another outstanding creation by the same dedicated fans who brought us the Rotterdam Metro Route and HTM Regiocitadis for Microsoft Train Simulator (MSTS), is a testament to their unwavering commitment to delivering authentic and immersive railway simulations. The model, while operating within the constraints of older graphics and technology, manage to capture the essence of this unique metro system, offering players a chance to step back in time and experience the charm and character of the RET Type R-SG3. With the disappearance of the platform hosting these creations, there's a real concern that these exceptional fan-made experiences may be lost to history. Preserving the RET Type R-SG3, along with their other creations, is vital to ensure that the hard work, passion, and creativity of these dedicated fans continue to inspire and captivate future generations of simulation enthusiasts. These virtual simulations are a treasure trove of nostalgia and dedication that deserves to be shared and cherished.
