As a MetaKnight player, he is pretty hard to counter. I am guessing he spams the B spin constantly with the corkscrew attack. The trick is to always be ready to jump. Neither of his 2 most spammable moves give him height quickly. Make sure you make him come to you. if you go to him, you will get move spammed while you are getting near him. If you play characters with range abilities, make the most out of them. :)
So I played as the Joker at E3 and It will not be enough to make me get the PS3 version. I personally prefer the 360 controls for the game. The controller feels more comfortable in you hand for the button combinations that you will be spamming the most.
For the Joker, he played similar to batman in that his movements felt big, heavy and slow, but he did not do enough damage for how slow it was. His killing blow attacks take longer than batmans and are harder to recover from.
Honestly, unless they go throw in a dark knight batman costume, it wont make me purchase any specific version.
I think Microsoft had the best conference. Project Natal blew the competition out of the water. The Wii motion plus just does not look so good compared to Sony and Microsoft's latest offerings. Even Sony's motion controller is not looking so good after Project Natal. If you look around online, there are some hand on impressions with Natal and Burnout Paradise, one is on kotaku and he was impressed. He said it was not perfect, but for being a prototype with a demo of a game not designed for project natal, it was quite impressive.
I went to E3 and checked out all 3 booths. Except for the new super mario brothers wii game, I was not very impressed by their booth. They had few games for the core gamers available. Sony had a good showing of God of War III but beyond that, it was mostly 3rd party titles that are on all consoles. Microsoft had private showings of Natal which from what I heard have been very well received. They had Forza 3 which easily stole the spotlight from a lack of Grand Turismo 5.
There is not yet. This follows the basic principal of Yahoo Answers. There is not a whole lot of information you would need from seeing if someone is online. If you are trying to contact someone, I would click on their user name and see if they have contact info listed.
We all knew that 4 would not be the last one, it is a franchise that makes money. If it makes money, there will be a sequal. I will be excited if it does not feel like some half attempt at continuing the franchise.
I guess we just gotta wait a bit longer to see how excited we really will be.
Personally, I will be excited if its good. Metal Gear 4 was a solid game, enjoyable, and would love to see the convoluted universe continue its story telling!
