Railway Empire 2 is a PC train simulator where you design rail lines, buy trains, transport cargo/passengers, and compete with rival companies. For players who’ve built extensive rail networks, what’s the biggest challenge in late-game—was it avoiding train collisions with complex junctions, or optimizing routes to maximize profit (e.g., transporting high-value cargo like oil)? Additionally, the game has a campaign set in different eras (1830s to 1930s) with historical events—Did the campaign’s story and objectives make the game more engaging than sandbox mode, or did you prefer the freedom to build without restrictions? Finally, Railway Empire 2 has improved graphics and AI compared to the first game—Do you think these upgrades make it worth playing if you enjoyed the original, or are the core mechanics too similar to feel fresh?
