The game needs an "undo" or "cancel" feature, to undo actions. It's very frustrating to (for example) move an adventurer to the wrong age, with no way to undo it. In face-to-face play, of course "undo" would be allowed. Another example: When I build or upgrade or downsize a building, it would be nice to visualize it by letting it happen, then undoing it if the effects were unexpected. On a real board, one can touch the pieces, lay down a building temporarily, and so on to help visualize what will happen, but on a virtual board you have to imagine everything. Of course, one could just play more carefully, but an advantage of a computerized platform like boardgamearena is that the computer instead of the player can do some of the tedious work.

Of course, if another player is involved, or any sort of random action (such as a card draw) has occurred, such a move cannot be undone. But being able to reset to the last such point would be a huge help. Even allowing only the most recent move to be canceled would be a big help, to allow a player to fix a careless click that ruins the game.

Through the Ages has a "cancel" feature like this, and it makes that game less frustrating and more enjoyable.

Please do it!!! It should be easy to add and it is sooo fustrating for beginners like me. tim2pet3 explained that perfectly :) :)

Pretty Please with suger on top...

Seconded. I'm basically learning the game the hard way, every special clause or UI decision cost me a game, which isn't quite fun to be honest.
