Third-party controllers have been a staple of budget gaming for decades, yet browsing the options remains a tricky task. BigBig Won is far from a recognizable brand name, but it is quickly garnering a good reputation with its Rainbow 2 line of controllers, which include the Rainbow 2 SE and the Rainbow 2 Pro. Both options are extremely versatile, offering an incredible amount of customization and providing players with a significant amount of swappable parts.
