My man Windy is exactly right. Maybe if Metroid were the only NES game available on the VC, yeah, it'd get a higher recommendation. But the fact is there are tons of NES games on there, the vast majority of which are less frustrating and more enjoyable than Metroid. Now, I don't expect everyone to agree with me that Metroid is a terrible game. Indeed, I thought that my opinion was one of the minority. Metroid is one of Nintendo's Big Three franchises (well, four if you include Smash Bros.)--how can I poo-poo all over the original game?
Well, for exact same reason I poo-poo'd all over the original NES Castlevania: it's horrible by comparison to its far better sequels and even contemporary NES games.
And Pale, dude, if you have to start from the beginning every time you die, that's not a "persistent world." That sucks. :-P
