So it looks like I'll be clearing out the event prizes tomorrow...once you get a couple of mid-level pollen producers (I use the ones you get from the red couch) you can completely forget about anything else and just merge 5 your pollenated ass off till you're done. In terms of the event map, this required only clearing the lands that comprise 'Europe' and 'Asia' on the stylized globe. Maybe it required less, but that's when I lost patience with clearing land, anyway.

Am I missing anything by not clearing the rest of the land on any of these event maps? I get it that the event with the limited stars required clearing all the land to reach the event points for the prizes, but with the exception of coins/crystals/gems, nothing form the event map itself carries over to the home map. Does anyone bother with the completionist stuff if it isn't part of getting points?
