Oh yes, of course. Like I said, these games are all several years old and have, I think mostly run their course in terms of full price sales, so I don't think these bundles significantly affect these game's future sales, and getting exposure to lots of people opens up opportunities for sales of sequels/future games.

Still, it'd be worth doing the maths on - if your game is still selling well, putting it in a bundle would be foolish.
