Nintendo Switch Online will be expanding next month and will be adding more classic games to the system. The service now offers NES and SNES games but next month games from the Nintendo 64 and the Sega Genesis will be added. The catch is that this will come with an additional cost or as Nintendo describes it an "expansion pass". The new membership plan will be added in late October. No word yet on the launch date or how much this expansion will cost.
Here are the games that will be available at launch
