Colecovision launch titles

The Coleco Vision launched in July 1982, and made a relatively big splash, selling about 2 million units, largely on the strength of its launch titles. Here’s a list of Colecovision launch titles along with notes about each game.

The strategy behind the Colecovision launch titles is pretty clear. Noting that the most popular Atari 2600 titles were ports of arcade hits, Coleco aggressively licensed arcade titles, starting with acquiring a license for Donkey Kong before it was even released in the United States.

The Commodore 64 is the best selling computer of all time. Depending on who you ask, it sold 17 million, 20 million, or 12 million units. And the generally accepted sales figure for the Commodore 128 is 4.5 million units. Who is correct? How many Commodore 64s and Commodore 128s sold?

NES launch titles

The NES launch titles were the 18 games released alongside the Nintendo Entertainment System during its North American launch on October 18, 1985. All of the launch titles belong to the Black Box series of games. The lineup was something of a mixed bag, but it was carefully balanced for a tepid American market.

When the NES launched, there were eighteen games available for it, a line-up that included four sports games, three light gun games, two ROB games, two racing games, an edutainment title, and six other miscellaneous games. Many of them were conversions from arcade titles, which is unsurprising since arcade games were Nintendo’s core business at the time.

He has a point.
