Not sure what you're getting at. Games like this existed before the peripherals, so it's not like the developers are developing these games with these specific peripherals in mind and you CAN perform without them, they just make it easier and more ergonomic. I played without them for years just fine, however I developed ergonomic injuries due to my hand positions and constant movements and the peripherals fixed that. THAT's why I got the mouse and gamepad, to address my ergonomic issues, not make gaming easier....that was a bonus.
Just wanted to put that out there. I hope the controller works for you as this is a great game IMO. If not, I agree with you, there are a ton of great games on the market and available.
