One possible drawback of this expansion is that it seems to be primarily geared towards players who work with their guilds a lot. Aliens will only attack guild cities at first (although Enge hinted that they might eventually expand alien activity to other locations). Players who tend towards soloing or casual grouping might not find themselves in guild cities very often. But with markets, goods can be globally advertised. Buyers can remotely purchase items, but they'll have to travel to the market to pick them up. Funcom hopes this new system might encourage visits to guild cities, where non-guild members can find themselves on the receiving end of unexpected alien hostility.
