Ok first of all, a suggestion for next time you make a thread title "Why I hate {insert something you hate}, try to list valid reasons.
You can't say I hate this because I just don't get the gameplay, since you aren't listing anything valid that you don't like about it.
Now, my thoughts on SG4 are the following;
Pros-
*I love the size of the map, I think it's the perfect size for any map, since the games aren't super long, but they aren't super short either.
*I quite enjoy the chest placement, everything seems to make sense where it is, and there aren't a huge amount of chests, nor are there not enough.
Cons-
*This map has been played OVER 9000 times.
*The buildings are pretty basic, as well as the terraforming.
