I am glad for you, tfishell :).

Update: My son loves "Pajama Sam in No Need to Hide when it's Dark Outside" :), it's the first one he has tried.

Also, I can confirm that the Steam versions (at least for Mac) are DRM-free too after download.

Thanks for the info, and the feedback!

Played Putt Putt Travels Time with my 6 year old last night, the animation on these is nice with a really detailed world interaction. Glad I picked up the lot and hopefully it comes to more outlets outside of Steam.
