Hello Community!

I would love to add the steam widget to collect wishlist entries. Is there any rule that prevent me from that?

Thx for any answer!

I don't think so, and in fact I've seen things like that around here.

Steam is one of the additional app store links you can add to your Edit Game page, along with the App Store, Google Play..., so doesn't seem like there's any policy against Steam (although adding a Steam link there doesn't result in a displayed Steam badge as it does with the other stores, so a bit of a mixed message...)
