It's obviously not going to be a huge source of income, but if it a few percent of revenue or something, depending on the amount of work necessary to make it happen, it might be worthwhile.
Example: I've been a fan of the Warcraft universe and lore, and I own a pile of Warcraft merchandise: action figures, posters, t-shirts, and collector's editions of every Blizzard has made a collector's edition for (I don't even play the new WotLK, but I like having the collector's editions for the art and soundtracks).
If he's got some customers are as rabid about his games as I am about the Warcraft universe, he could at least increase his revenue by a few points, even if it's just simple stuff like cloth maps, t-shirts, and soundtracks included with a Collector's edition of a game.
I don't think that's unreasonable. Obviously it's not going to overtake the rest of his business, but it could be an additional source of revenue, and even advertising (T-shirts are walking billboards), people talking about the "awesome" inclusions in collector's editions. Stuff like that.
