It was interesting reading all of the replies here. I do agree that 1.2.3 is extremely hard to learn, the numbers kind of prove this. 1.2.3 has been downloaded well over a million times, yet we only have a player base of 50 or so people who have stuck with the game. And oddly enough, almost all of these people who have stuck with the game started playing at the same time, right when 1.2.3 was released. I think that, at the time, no one was quite good so new players had room to breathe and learn the game at their own pace. Then as time progressed, the pros got better and better and better until we reach our current point when a new player has almost no chance of learning the game. The problem isn't so much that ESF is hard, all you really need to do is fly into other people holding right click. The problem lies in how good people have become at this system, it's gotten to the point where if you want to get good at ESF, you're going to need 5 months of dying over and over with no chance of even getting a hit, let alone a kill. And after those 5 months, you'll probably only be a decent player compared to the guys at the top.
The answers to all of these questions lies within how hard it is to learn how to play ESF.
Early on in 1.2, the game was much easier to learn. Because everyone who was previously good had to essentially relearn the game, everyone was on equal ground. Players never felt completely helpless, as there was no one good enough yet to make them feel like they had no chance of winning.
Right now in 1.2, the game is nearly impossible to learn. People have mastered the current mechanics of the game, a newbie coming into ESF will die repeatedly until he asks how to play. The playerbase, tired of the same question over and over, will either not respond or tell said player to RTFM. Of course, the player had no idea there was a manual for the game, it mentions it nowhere. But regardless, even if this new player does read the manual, he is facing what is in his mind an impossible battle in learning how to play the game. New players will have no chance of winning vs a seasoned player and, lacking the crutch that was HOWing, will quit the game.
You see, HOWing was a necessary evil. I realize that everyone hated it at the time, but it really was responsible for a lot of people sticking around and learning to play the game.
