So how do you reach those buttons with your HAND OVER the buttons?
With my Logitech Pro mouse, my thumb can barely handle the 4 buttons I have there, plus the usual 2 buttons & wheel.
There is where the keyboard or another controller comes in handy. Speaking of which, I actually HAVE This device:
Which I haven't used in years... hmmm wonder if it'll owrk on Windows 7. I haven't used it in over 10 years... I use about 16 keys on my keyboard + mouse, so I think I found it more in the way than anything else. Its a left-handed movable base controller. So while the "mouse" area moves in 8 basic directions, its attached to a base so it doesn't actually go anywhere. So that can replace the WASD keys, but I think its TOO slow for many players. I use my mouse to control movements (LB forward, RB rev) and move movements for direction. Keyboard is for shooting, inv. weapons... etc.
Another ODD MS joystick I have...
Notice how it looks like someone took the TWO Wii controllers and attached them together! This thing was made around 2000/2001. You were supposed to control 3D space movement right the right controller, which meant the left one moved all over the place... and worse, the movement was very restricted.
