I think you've mixed some things here DiM. You are measuring popularity in terms of playing.
that's what popularity means.
a video with lots of view = popular video
an artists with lots of records sold = popular artist
a map with lots of games = popular map.
of course it's not a perfect system.
i'd rather see a formula that also includes number of rounds played per game or number of unique players or actual time spent playing.
because for example 100 doodle games have a total round count of 250 while 10 world 2.1 games might even go for 300 total rounds.
also on doodle the average round time is 30 seconds while on world 2.1 is probably 2 minutes.
The Poll is measuring 'Favorites.' While Doodle Earth may be popular for game playing because it is quick, that doesn't necessarily make it someone's favorite map as say World 2.1.
That is my understanding at least.
so just as i said it's fun poll that measures favourites not a serious one that measures popularity
