After the success of Torchlight on Xbox Live Arcade, a similar port of the sequel would seem to be a foregone conclusion. Unfortunately, there's one rather large obstacle: it's just too big.

According to Runic Games CEO Max Schaefer, Torchlight II's co-op multiplayer; wide range of terrain types and variety of hub cities makes it too big for the service.

"With Torchlight 2 there is a little more complication as far as just being able to do a straight port, as we did with Torchlight 1," he told Eurogamer. "In all likelihood, if Torchlight 2 gets to the Xbox it would be probably fairly comprehensively redesigned."

"We would have to be redoing the interface for a console release anyway, just like we did with Torchlight 1, so it would probably make sense to do something more specifically tailored to the Xbox."

For now, Runic is focusing on the PC version, which will be followed by a Mac port. But they're keeping their options open, with possibilities including a full retail release (though no formal discussions have taken place on this front).

"Torchlight on Xbox Live did very well for us. I think it's the number one revenue game on XBLA for the year so far. We missed out being the top for units sold to Full House Poker by a little bit but they cost less than we do," Schaefer said. "It was definitely a profitable and valuable experience and we're happy with the results."
