Oh, thanks for the heads up, lll look into that. Indie royal is Desura-based, and deals with that version of the game, so its just the groupees greenlight bundle i need to look into.
For what it's worth, the Valve guide also suggests against big sales on your game within the first two months of launch. Though I understand you're going to try to leverage this into Greenlight campaign support, so I don't know.
Personally my opinion is just that, next to the entire debate on bundles devaluating indie games, I don't see that much opportunity for exposure. I look at some of these lesser-known bundles and they just strike me as a list of games I've never heard of before and are probably not even that good since they're already "bundle fodder".
