The interactive scenes have an improved user interface as well. As usual, it has to deal with the challenge of showing a lot of information, but with a smaller screen than the original. So if you want to see if you can afford to buy a treasure, hide the text (in the iOS version, this is always by tapping on the illustration). This will reveal the six statistics that were always shown in the desktop version.
Or, tap the Info button. This shows an information panel, where you can look up a clan or tribe (using the same filters as in the Relations screen). It also reminds you of the calendar, so you can think twice about raiding during the harvest.
New in the iOS version is access to the saga from an event.
