megaman x2 and x8 and battle network 1

Classic. Without a doubt. There's just something magical about it. It's one of the purest examples of what 'video games' are.

Probably X, but I've only played X and classic so I'm very very biased, I have no idea if any of the others would be my cup of tea.
Also, I'm surprised nobody has brought up Egoraptor yet.
