When rumble effects came to gaming it turned a fun experience into something immersive. Now the feature is so common we have it in the phones we carry in our pockets, and its been in home consoles for close to two decades. Yet PC gamers still need to spend extra if they wanted force feedback. A company called Tavitas has just such an offering in the works with the Sinister gamepad, and promises to bring it for around $100 when it launches in six months. Even better, you can take buttons out and move them around, changing a gamepad configuration to your liking.
