Spending too much cash just to become gosu on an online game is, IMO, not worth all that much, unless you can do it legitly (or illegitly in secure fashion) and get a good deal out of it.

In my powerleveling days I made thousands of dollars selling fresh WoW 60s and 70s. But that was only a sideline, in any case. Most of my online trading money was secured by selling currencies. Especially Gaya gold.
