Now the idea of it was good, the intentions were good, but the final product was very unbalanced and buggy. And the player base, oh god..Most of them are a bunch of whiny, impaitent, rude, ADD children who just want to make big bright lights in a small map, following it with a "OMG LOL". People who usually play EVM get "bored" with ESF.
ESF is taking awhile because the quality is being upped dramatically. When quality is upped, it takes longer to create, such as percise aniamtions, crisp models, and an attempt to be bug free. There is also many other factors they may consider and would defiantly not take just a couple of months, From what I have seen, they are comming a long great.
