16. An Arcade Stick
This accessory is a must have for those who enjoy games such as Street Fighter V. Not only does it give you that arcade feel, which the controller doesn’t offer, but it also gives you that extra edge when playing. The only down side is that it's not a cheap accessory and will set you back around $300. What's more, there isn't a huge catalogue of games to fit this genre, although there are still enough to warrant the purchase if you're a big fan of this type of genre.
