I'm still in the process of playing through this collection. I can already say that I wish I had followed this series from the beginning. I can't imagine there are too many people out there in the same situation but, if you have never played any of these games and you are a fan of the X series then you absolutely have to complete these games. I don't want to give away the story details but know this; the mavericks that you fight will make you think harder in order to stop them. At least that's what I thought. But I don't want to document any of that information here because once you know the tricks the games become easier. So far I've completed two out of the four Megaman Zero games and it was already worth the purchase. When you complete a game you get the option to play again in hard mode so that will give players some incentive to replay. Also, you are given a rank for every stage you complete and this goes towards your overall rank. There is just too much detail to cover without rambling on and on about this game. Bottom line; if you enjoy the Megaman X series and have all of them or the collection that Capcom made then grab this too.
