I am also a big fan of the Lunarian bad guy for 70% of the game is your brother story line it's unpredictable and challenging.
The DS remake is amazing.
Yeah I think changing nammingway was awesome to but the new grapics just blew my mind, I never beat Proto-Babil though cause my DS got stolen is he really hard.
Proto-Babil? Well...second half of the fight with Divine Judgment spamming isn't very fun.
If you steal Dark Matter from Zeromus before using the Crystal & start a new game+ you fight Proto Babil on that wierd face on the moon.
