I'd like to use a PS3 controller, but then there's a button issue because it needs to be held with two hands.
I'm still trying to solve this mystery myself.
As I noted in the other thread, I typically use a rather unorthodox key bind set up when playing MMOs where I do all basic movement with the mouse and only use keys for strafing--and shift my "home" more towards the middle of the keyboard to allow access to a lot more keys.
It actually works well for away teams. But I prefer to use the FPS mode anyway. It's probably a little less effective, but it's way more immerse.
But my keybind setup just doesn't work for space travel. I've tried altering it several different ways. But there's just too much that needs to be controlled movement wise. The biggest issue I've had was finding away to comfortably mitigate speed. I've been using the scroll wheel on my mouse, but that's just too inaccurate--even with the scroll speed set as low as possible.
I'm going to try the keypad approach next, but I'm not holding a lot of hope.
