It's funny, every time Intellivision releases a new video it's 1 step forward and 2 steps back. The latest gameplay trailer from Intellivision features games we have never been shown by Intellivision before but, sadly, they have been seen before. How is that possible you ask, because the showed off several recycled games and passed them off as their own.
Now, to be fair, these games were not explicitly stated to be Amico originals but that was the implication of the video titled "Intellivision Amico - 10.10.2020 Gameplay update!" The description on the video goes even further by saying "Here is a quick look at a bunch of games that are currently in development for Amico and will be launched in Q2 of 2021. Please note that nothing shown is in its final state and are all a work in progress." So, at the very least these are supposed to be games in development for the Amico, which would not be the same thing as games in the process of being ported to the Amico.
