Perfect Dark Zero is GOOD

[A Black Falcon]

Soul Calibur II? Fun, but somewhat simple... it seems easy for someone who isn't as good to win because you do so much damage, so it takes fewer hits to kill... and it just feels less strategic than a good 2d fighter like a Capcom or SNK one. I'd rather play CvS2... because there are no SNK fighting games for Gamecube and I don't have a PS2 or Xbox.
Simple?! Dozens of moves, guard-impacts, combos, weapons (unlock all the weapons and it gets more complex), side-stepping, throws, hi-hits, low-hits, mid-hits, blocking...I have no idea what you're talking about.

You obviously haven't given Soul Calibur enough time otherwise you would know how deep of a fighting game it really is (not Virtua Fighter deep, but a complex game for sure). It took me months to get good at Ivy (one of the tougher characters to learn), but now I can own just about everybody I play against (save for my friend who is VERY accomplished with Voldo). I don't even get close to breaking a sweat on newbies who button mash.

People who don't know what they are doing win more often in Soul Calibur II than a Capcom or SNK 2d fighter. It is also not that hard to win... I beat it and unlocked everything and have beat the arcade mode on max difficulty with various characters (Seung Mina is my favorite character, but I've also played quite a bit with others... Cassandra second, but also Link, Nightmare, Talim...)... yes it's got a complex system but you don't need to learn most of it. You should know a guardbreak move for the character, at least, though... but really, in complexity it doesn't come close to a King of Fighters, Capcom vs SNK 2, Last Blade, Virtua Fighter, etc.

Actually, I think I even like Mace more than Soul Calibur II, though they are very different games, Mace being quite slow paced vs. Soul Calibur's speed... Soul Calibur is certainly a good game, though. Quite fun to play. I just like some other games a bit more. (kind of like SSB in that respect, I guess... though SSB is a bit better on the 'play indefinitely even if you're not really having fun but aren't hating it so much that you can't keep going' front)

SSB: like most fighting games, good players win, new people don't. Sure, it's more approachable because of the lack of special moves to learn, but still, from what I've seen the good players still win the vast majority of games...
