Delirious

Railroads certainly lacks the depth of it's predescessors. However it is a fun game to play. The small maps will only take an hour or so to conquer, whereas games like civ could take up many joyous hours.

Also the QA department didn't really do a good job as there are many major bugs such as being able to buy and sell stock over and over for easy profit (yes it works in multiplayer)

Overall with the simplistic nature of the game, I think Railroads may be geared more toward multiplayer.
