To add classicness to the feel, you can do the following things on your own:
1. Buy a K6 or Pentium 2 computer with a Voodoo card and 32 MB or RAM and play EQ on it, with a 14 inch CRT monitor and a ball mouse. If you get more than 10 FPS, make sure to throttle it in the options (ALT-O) to 10 FPS max. SB16 for classic sound, AWE32 or Gravis Ultrasound if you want to simulate baller 1999 setup.
2. Use a 14.4 modem, maybe a 28.8 to connect to the internet. Use
software like this to add some packet loss, random lag spikes and generally make the connection unreliable.
2b. For full immersion, put your modem on a programmable AC plug and make it disconnect at random times to simulate your sister or mom calling a friend in the middle of your quad kite making you die horribly.
3. Use a 640x480 resolution with the old UI
4. Only use the full screen mode
5. Drink 4 large glasses of hard liquor such as whiskey or rhum every time before playing to simulate general cluelessness about the game and Norrath.
6. Send me $15 every month per account (PM for Paypal). This is critical for immersion.
7. Enjoy!
