Aren't Zelda I and II on GBA just from that classics series or something? Aren't they straight ports?
Link to the Past is the best game in the series, and the GBA version has an extra dungeon and Four Swords, which I recently managed to play with some bros on an emulator. There are minor changes, which have been mentioned, but if you think you can get some Four Swords going and enjoy that extra dungeon, then why wouldn't you?
Link's Awakening is also remade on GBC as Link's Awakening DX. Might as well play DX. It's the same thing with an extra dungeon. I just want more content.
I never got into Metroid before but have been playing the first one today. I would have tried Zero Mission but everything I read about it seems to show it is actually a very different game that does the same plot. I expect it is easier than the original game, too, because for some reason I find Metroid 1 to be the hardest game ever. I can beat Zelda II, I can beat Ninja Gaiden, but I can't even come close to feeling like I'm even getting passably good at Metroid. I can't advance at all. I don't know what the hell my problem is, because people don't act like Metroid is the hardest game ever, but it clearly is. I even got pretty far in Metroid II before deciding I might as well play the original first, I didn't find Metroid II hard, but people act like it's almost as hard as the original. It's totally not.
What the hell is the matter with me? Why can't I get good at Metroid I?
And no, the lack of map isn't my problem. I can memorize all that shit, I just can't make it past enemies without getting hit and losing the one hit that you begin with every time you die.
