We have a lot of threads here to talk about games we're playing, or just bought, or whatever, but I think there should be a place where people who are really passionate about a game or other gaming-related thing that they feel hasn't gotten enough love to make their case for why other people should check it out. Make this a place to argue in favor of your favorite niche product in order to recruit others to it.
My entry is the Power A Pro Elite Wireless PS3 controller (
Amazon link).
I've never liked the Sony Dual Shock Controller for a bunch of different reasons, so for a long time my PS3 was used as a last resort, for games I couldn't get anywhere else. But once I found this controller, that all changed. Unlike the Dual Shock, it's contoured to fit your hand instead of Sony's angular design, and it also fixes issues with the shoulder buttons, so that pressing L2 and R2 works without any issues. It connects wirelessly through a USB dongle, which has a passthrough for a cable to charge it. Because of this, my PS3 has gone from last resort to being my primary non-Nintendo console. It's such a massive improvement.
