A couple of Xbox Live Indie Games developers have seen notable increases in sales of their games, due to two separate forms of cross-platform and cross-game advertising.
Going Loud Studios founder Ben Kane revealed that, since being a part of Gamasutra sister website Indie Royale over the weekend, with a PC version of his games DLC Quest and Lair of the Evildoer available via the latest bundle, sales of the Xbox version of DLC Quest have quadrupled.
DLC Quest had sold 134 copies on XBLIG the weekend before the Indie Royale bundle -- however, during the bundle this past weekend, the XBLIG version saw 506 sales in total. The game has been available via XBLIG for around four months.
"To move over 500 copies this past weekend on Xbox is nuts," he said. "It also has a pretty big implication -- you can do cross-platform advertising or word of mouth and have an effect on 360 sales."
He continued, "There's sort of been this age old wisdom that you can't really successfully advertise for XBLIG on PC or mobile, because there's just too much of a gap between looking at something on your PC, and then going and playing it on your Xbox."
However, he says that this past weekend has shown him that "at least to a certain extent, it can be done."
Elsewhere, the developer behind Minecraft-inspired XBLIG hit FortressCraftrevealed via Twitter that another of its XBLIG games, Steam Heroes, has sold more than 10 times as many copies as it had previously, simply by offering an unlockable item for FortressCraft when you buy it.
Back in October, the company added a special in-game item for FortressCraft, that is unlocked by purchasing Steam Heroes. Sales of the game immediately rocketed following the inclusion, with 10 times as many people buying the game over the next couple of months than had purchased it over the 12 months prior to that.
