Rough estimates of revenues from retail sales of "Half-Life" bring the total gross revenue for the game, and its subsequent supplements, to around $200 million, according to Warren Gouk, vice president of mergers and acquisitions at Cascadia Capital LLC, a Seattle-based investment bank.
Tack on another several million or so in merchandise sales, and you may be in the ballpark in total revenues generated, Gouk said.
That money is sliced between Valve, its publisher Sierra Entertainment, and numerous retail outlets.
"If they did do that much, it would put them among the elite video-game developers in the world, and 'Half-Life' would be one of the hottest games ever," Gouk said.
Newell wouldn't give an exact figure on how much the company made on "Half-Life," but said "a good ballpark number" is about $20 million.
"We have pumped nearly every dollar we made on 'Half-Life' into the company," he said.
