I like to maintain the opinion that all maps are good if they are cared for by their creators. If a creator put all they could into a map and thought it was good enough to share with the public, who are we to say if it is good or bad?
Don't get me wrong, there are plenty of maps that are better than others, but no map is truly bad.
Also, I voted for every single map above, not because it is bad, but because of factual reasons.
Fortune Island -- Probably one of my personal favorites. However, seeing as the terrain is clearly world painter and that the best build looks like a blown up village (the one's that you find in default generated terrain) it should not stay on the servers. It isn't a bad map, but what people got to realize is this:
You can like a unpopular map like Fortune Island more than a popular map like Holiday, but if there are obvious building/gameplay errors should Fortune Island really be kept over Holiday just because of your personal opinion. This is what we are seeing a lot of, people getting offended when a map they like comes up in "remove" threads like this one. However, it isn't about what you like. I love Fortune Island, but I still think it should be removed.
We all have our opinions, but what you guys need to try to do is think beyond yourselves and attempt to think about what is best for the community as a whole and not just for you. You could like Fortune Island better than SG4, but does that really mean that it should be kept instead of the most popular map of all time? Think about it, if this rant made any sense at all.
