Are there any games out there for the blackberry (i have a 7230) that you can play online? graphic games, nokia programs, MUD's, anything. Any ideas anyone?

We've been looking to connect Medieval Kings Chess into existing Chess servers.
For now you can play online at:

http://www.magmic.com/medievalkingschess2/battle.php

against people playing on BlackBerrys over-the-air (it's a Java applet on screen, wait for it to load). You can download a trial of MKC II direct to your BlackBerry at bb.magmic.com

Nothing else? I tried that MUD mark talked about, but the responce was sooo slow and with tons of people walking in and out, it got confusing. Any other suggestions? I will be on a trip online with just me and my blackberry (and a charger) for 5 days.

Or any RPGs?
