200 Mbps is quite a decent speed for playing online games. You will get around 100 Mbps of upload and 200 Mbps of download speed, which should be sufficient for all kinds of games, including heavy ones such as COD Warfare and PUBG. What's more important than speed is the distance of your home from the game's server. You could be using Gigablast plans and still be getting 150ms ping if you live far away from the server. The experience shall remain similar on WOW! Internet 200 or above plans unless you're having a lot of devices sharing the internet.
