Konami is one of the biggest video game producers in the world. Its most popular series include Castlevania (Akumajo Dracula), Contra (Gryzor/Probotector), Metal Gear, Silent Hill, Gradius (Nemesis), Suikoden, International Superstar Soccer (eFootball/Pro Evo), Dance Dance Revolution and Frogger.
This lists includes games developed by Konami and its subsidiaries Team Silent and Bemani, and Konami-published games developed by others for Konami properties. It doesn't include every single game or regional variation because that would be mental. A lot of these games have different regional names. Don't blame me, blame Konami.
