I'm looking for a database script... I think

I'm not exactly sure if that's what I need or not. You see, this is what I'm doing... or want to do, rather. I'm an avid game player and Square will be releasing Final Fantasy XI Online next year for the PS2. I wanted to set up some sort of database where people coule sign in and submit unique/rare weapons, armor, and items they find, stuff like that. I also hoped to include in the database the various quests that would be in the game, but I'm not sure if that would be possible. I was looking for a database script that would be pretty customizeable in terms of the layout and what I could put where, and it would allow users to log into it. Possibly rank each other, I'm not sure, so we could keep the number of fake item entries down. A search feature would also be nice, but it's not necessary.

As you can see, I'd need this thing to be really customizable. I'm not even sure if I need a database script, or if I can use one. Should I just be setting up something else to do all this and skip the CGI/PHP scripts? Are those a lost cause?

I appreciate any help anyone can offer. I really need something, this is entirely what my website is based on. Without this database, my site won't exisit.

Here's the site that inspired me to do this database thing. It's another database. Gives you an idea on how much customization I need in this thing...

Their's is nice, but it's really buggy sometimes. They have a database for Phantasy Star Online as well and it never works right, I wanted to provide the gamers with something at least halfway stable, plus a few more features and maybe a little better layout if I could. Just thought I'd provide you the link.

Heh, sorry it was kinda long.
