quite honestly i think it would be awesome marketing, much like their free weekends (which is actually how i moved from A2 to A3 being able to try A3 before buying it. it would give those who haven't bough the DLC and are skeptical about it to explore the island, see the quality and if it suits them. it could honestly convince more people to buy the DLC so they can play when it comes out, i know for a fact it works because as i said, i started playing on a free weekend to give it a try and bought it in the following days.
