Yar, Zero’s ending in X6, so I hear, is supposed to happen at the very end of the series, and not X6, making it canonical. I don’t understand why they did that but whatever. We’ll just see if they make that happen.
What sucked most about X6 was that it had TERRIBLE unbalancedness for X. It seriously was impossible to finish the game without any armor. Why do they even give you the option to do that if you can’t beat any levels with it? It’s totally bogus. The game was more balanced for Zero as far as I can tell, but he also had the SPINNEY OF DEATH so I dunno. I’m an X specialist, not a Zero specialist, so someone could comment on its balance better than I can.
