The 8th generation of portable game consoles, commonly considered as having began in 2011 with the release of the 3DS, and ending anywhere between 2019/2020 (discontinuation of the last 3DSes and the Vita) to not having even ended at all (with the Switch Lite still being produced, if you consider it to be 8th generation). Regardless of this slight end-date confusion, the 8th generation was similar to it's predecessor in possessing a great variety of EOPs, plus a lot of interesting “non-competitor” devices providing a variety of EOPs and related things.
