8) Dreamcast – 514,000 units sold in 14 days
Speaking of failed consoles with bright beginnings, Sega exploded back onto the scene back in 1999 with its highly anticipated Dreamcast console. This was the machine that was supposed to save Sega’s blushes after the Saturn had completely bombed during the previous generation. Our seven-day scale slightly underplays Dreamcast’s nascent success, which actually achieved over 300,000 in four days for a grand total of 514,000 in two weeks. For consistency, however, we have divided that number by our variable – averaging to 257,000 over those initial two weeks.
7) Wii U 400,000 units sold in 7 days
The Wii U might have ended up as one of the worst selling home consoles of all time, but its early fortunes were markedly different. The Wii U flew out of the gates, recording figures that almost rivaled that of its predecessor. The Wii U is, perhaps, a reminder that a console’s early performance is not an indicator of long-term sales success. The Wii U’s drop off would ultimately contribute to Nintendo reporting its first operating losses in 2016.
