According to the video, it comes pre-loaded with 1000 retro games, and you can load your own Retro ROMs as well. I'm guesing most of the games are older games from the 1980s and 1990s.
Sinclair ZX indiegogo page does not mention any titles, so people who buy this console may end up with a lot of games which they don't like, or most the games already freely or cheaply available from Steam, Gog, iOS, and Google Android.
It maybe more worth it to buy a Google Android handheld like the Nvidia Shield handheld since Android already has great games for it like Final Fantasy 9, Sonic, and Knock-offs which are unofficial clones of popular console and PC games like Counter Strike, Team Fortress, and Call of Duty.
It could be a good gift for retro gaming fans who are not very tech savvy to find 1000s of licensed retro game on the internet, and install the games on their PC, console, or smartphone.
