If you're going to limit the amount of upgrade I can have at a time (with warehouse space) it should be possible to sell upgrades or at least dump them, just in case people make the wrong choices.
Yes, I know that the game is called decision for a reason but restarting shouldn't be your only option if you accidentally use all your space on business upgrades and you're too weak to capture a factory (for example)
Well, it now looks slightly less like an Arcomage clone, but i think it was a better game when it was a little closer to its source, they would have done better to introduce a few more interesting cards than just pretty it up some and leave the gameplay identical.
erg - don't understand - what are he duplicate articles ? Don't want to drive anyone to madness !
