No real incentive to play summer? Well here is a potential solution; a summer exclusive feature that actually makes sense and is easy to build any new content into. For instance if people want a summer version of the Walrus Hunting Party then this lake could perhaps dry up and expose a dry, cracked riverbed inhabiting scorpions, snakes or perhaps even destructible termites mounds. - Tons of potential. The lake could then fill up again when it rains in the Autumn and will be dormant until the next summer. I'm not sure how the transition between lake and no lake would look and how the creatures can spawn without just blinking into existence, but it's an idea. Note-able comments:
