Here is a short list of ways to know if you are addicted to AC:
1) You scream and repeatedly ram your car into piles of rocks while driving, mistaking them for Granite Golems.
2) Your coworkers wonder why you stand in your cubilce, make wierd gestures with your arms while shouting "Shurov Thiloi" at 6 pm instead of driving home ike a normal person
3) Saying Shurov Thiloi works for you.
4) When somebody asks what you did yesterday, you launch into a long winded sry of your hunting in the dires before realizing they meant school.
5) Everybody thinks Billy at school is cool because he brought a hand gun, so the next day you bring an exact replica of the Sword of Lost Light because you think it is 10x as impressive.
6) You get fired from work, then arrested because you are found writing down the certificate numbers from the AC CD's in your local computer software store.
7) Your annual source of income is the money you get from ebay people buying your stuff on AC
The people on ebay buy you a car because you are generating so much money for them through your AC sales.
