Any sort of in game currency where there isn't any value isn't going to be an issue since, well, there's no value. Now I know WoW gold is sold by Chinese farmers, but over all it is a zero value item. Blizzard doesn't allow sales, they'll ban you if you buy or sell, etc, etc. It isn't the kind of thing anyone buys as an investment or speculation or anything. It also isn't worth very much, and you find most IRS rules exempt things under a certain amount.
Particularly if YOU don't buy or sell it then there isn't really any issue. They aren't going to come after you for something you never exchange for currency, if for no other reason than they aren't going to monitor it at all.
In general game currency is likely to be left alone just because the amounts aren't likely to get that high. Plus most games have a highly inflationary economy. There is no limit to money, there's no "Horde Reserve Bank" that issues gold. The game just generates it whenever you do something that is programmed to give gold, and you can do it as much as you like. So buying gold to hold on to would basically always be a money losing proposition.
