Some things I want to say.
1.) I never had that lag on moon base that everyone talks about.
2.) Lag and delay are the same thing. When a youtube video is lagging it's the same thing as delay. There's a delay between you and the server and that's what lag is. A delay where everyone freezes and then you end up dead because there was a lag/delay with the server.
3.) Lag/delay are annoying but not the main reason why people quit FFT when WebGL came out. The huge problem with WebGL is the extremely low framerate. It's the most frustrating thing, plus sniping is impossible. The game is 100% different with the low framerate. The low framerate absolutely needs to get fixed for the game to progress and make money. As it is there are a bunch of other good free shooters out there that have high quality graphics, for instance Warface.
