A couple of observations.

The “Mars People” from the Metal Slug series strongly resemble the top-row aliens (second from the bottom, here) in Space Invaders. This doesn’t seem like a coincidence to me.

Samus Aran’s space ship, from the Metroid series, bears a close resemblance to the enemy ships in Radar Scope — the early Space Invaders clone from Nintendo (which flopped and was later reworked into Donkey Kong). This is probably a coincidence. Maybe, however, not!

EDIT: HA HA

“‘Warners is afraid that Revolutions won’t sell very well because of the word of mouth on the movie. The only way to make the money on sell-through is to package it with the other two.’ The retailer went on to say that the number of requests for the film have dropped significantly since the film’s opening day.“
