I recently bought VA and have been slowly plugging away at using the MS TTS to give voice feedback in game. I've started putting in custom responses so that it feels a little like an HCS voicepack. Obviously I have a long way to go but with the power of VA I think I can give Ensign MS Zira a bit of a personality.
Please bear in mind that the keybinds are very customised and not at all default (i.e. I use a HOTAS and a joypad for control of the ship and ground vehicle.) My Hotas is a beginner setup using the Thrustmaster Hotas-x which isn't great and its a complicated setup, but it'll do till I can afford a better setup.
Anyway, let me know what you think of my humble efforts so far.
