Need for undo functions for games with non-obvious interfaces

[Sweetdaddypete]

Hello to the site administrators,
I have hit two games where the user interface isn't clear and lacks undo functions - Caylus(favors) and Russian Railroads(bonus & objective, switching trains around during new aquisition). I think you should look into adding undo functions because making a mistake can ruin a game which isn't exactly short.

It's incredibly frustrating to make a mistake at the 3/4 point of one of these games because the interface isn't clear and have no ability to undo.

Regards,
Peter

I second this. I want to be able to undo an action when no new info has been revealed by the game or any of the other players.
