Mate all that hotas stuff is a gimmic. You don't need it. I have been playing since the PB launch with decent gaming mouse and a razer keypad and I honesty reckon it's a superior setup to anything else, particularly joysticks. Joysticks IMHO are seriously overrated and don't allow you aim with same precision that a mouse does.
Mouse can be quite an underated control device... however..
A well setup HOTAS System with YAW twist (not used) or Peddle (not got)
can give a REAL Sense of control, a mind tricking feeling to give you a strong sense of being in control that a mouse and keyboard don't always give.
Couple it with a good oculus Consumer Unit (when out) or a TrackIR or EDTracker and the game becomes even more fun to play..
Not easier... not better necessarily... but a new degree of fun.
So do you need these to have fun? No.. but they really can alter your experience positively and potentially in some cases negatively.
The advantage of these devices over others is negligible and comes down to player skills... A good player on mouse and keyboard can certainly take out a hotas, oculus combo lesser skilled player.
This debate will answer itself IN GAME and I hope I am on the winning side!!
If anyone wants a shot of my hotas... I do like to take it to public events like Fantasticon, Lavecon.. if you're in attendance.. just ask any of the volunteers to have a feel of psykokow's hotas.
