Hard Drive is still an indefinate answer…Most likely between $40 to $70 though. There are no other add-ons announced yet, except for the already released Linux kit. I believe there is a thread in the FFXI forum related to this if you need more info…so, this thread should be closed soon.
First of all, no hard drive has been released, it is not required for a dialup user. When the hard drive is released, you will have to put it in the expansion bay, but the network adapter will be required to use the hard drive (since it acts as a secondary adapter for the hard drive). Next, so far with the online games I have tried, things seem to be running somewhat smooth, however most of the game networks are not fully bug free, so sometimes you will find a ‘check to make sure your adaptor is properly installed’ (shame on you EA for making me disassemble the connection based on your false error message) or a ‘connection dropped’ message because of this. So far, the working game networks work as so. If you are dialup, you are connected to the ‘dialup’ server, in which you can chat and start games with other people, but the downside to dialup is that it is usually a much lower amount of players allowed per game. I think some games will allow up to 4 though. Once you set up your group of players, your systems sync up with each other in a direct link between only those systems (free from the game server) and you play againsed each other that way. Lag is only sometimes an issue, about half the games I played had a couple pauses during the whole game, the other half was flawless.
Unfortunately I don’t have broadband so I cannot test that capability. Keep in mind you will need a memory card with about 135k free on it. I suggest you buy a sharkboard (or any plug-and-play usb keyboard should work) so that you may chat and type in regestration information much faster (no money, just screen names and passwords). Appearantly most game companies as I said will be offering their servers for free, except for companies running servers that will take heavy stress (like Squaresoft for Final Fantasy XI) due to the overwhelming amout of players and style in which the game is played.
Virtually any Internet Service will work with the Network Adapter, if you have a router and a broadband service, just add your PS2 to your home network and configure it for your service (or use the automatic setup). If you have dialup service with a special client (ex. AOL), just select your service in the adapter setup and enter your user information. If you have a dialup service with nothing but the standard PPP dialup networking, then just select other and enter the information in (you can copy it right off of your computer).
I would like to conclude this by saying that it is worth buying the network adapter even if you decide not to pay for FFXI because there are many other fun games out there that will surely be online capable. Happy gaming with friends and strangers!
