You should try Dig Dug 2 sometime, as it's an interesting take on the gameplay. The first Dig Dug is still way better, though. You should try Galaxian just to see how it evolved into Galaga.
Yeah even though Nintendo is one of my favorite game companies, they do things sometimes that I don't always like. I can see both arguments being valid in this Namco vs. Nintendo tussle, though. Namco was right to be mad at Nintendo's policy since they were such a staunch supporter right away, but Nintendo also had to be stubborn about their rules so they could be fair to ALL third parties. But one good thing about Namco is that they've always been versatlie and open to change, so they just go to where the money is usually.
