After being gone from gaia for 2 years or so I played zOMG for a while but was wondering if I could reset it so that I start from the beginning again. Or do I have to create a new account on gaia inorder to start from the beginning of zOMG again?
You can't "restart" it. Usually if you want to start again, pretend you just joined and rid the knowledge you know of zOMG now, and perhaps if you want to go even more to extremes, salvage all rings except the Guns, Guns, ring. Otherwise, you will have to make a new account to completely start over. Like Quests, Null Chamber places you can go, and rings.
