Possible newcomer
 

I read the sticky above which says I need EQ Titanium to play EQEMu. I'll assume that even though I have all the expansions up to PoP, I still have to specifically have the EQ Titanium box.

I'm going to go research the price, but if someone else knows that the average cost for it and wants to post it here, I won't be heart broken.

I'm also wondering if addons/mods are supported by EQEmu. Thanks very much!

The average price of Titanium w/Account Key is roughly between $0.01 - $20.00. I say a penny because some people on ebay may just be trying to give them away to get rid of stock as it is out dated.

By mods to you mean like UI things. If so, those are client side stuff so you should have much of a problem. Now if the UI tries to use features not yet available in the emulator, you may see some things not like Live, but most stuff works like maps, and things.

As far as Server Side mods, you have to make any sorta of (added) functionality. Some people create things like new rulesets, more PVP styling, special items and mobs, but most stuff is on your own. Pretty much everything is opensource so you can edit to your hearts content so long as you give credit where its due.

Hope this helps out, and welcome to the community.
