A great idea would be to sell not only games but also music, art, assets and other things you have to help other devs and artists!

Just speaking as someone who buys way too many a robust selection of games pretty often:

I'd be less likely to buy the bundle if it was a mix of videogames and physical games or game assets.  I really only buy physical games, largely because I have the hand-eye coordination of an overcaffeinated warthog.  If there are videogames in a bundle I'm looking at, most of the time, I don't even download them.  Same with predominantly horror games -- it's a no-go unless there's some other compelling part of play.  (I'm still afraid there are demon clowns under my bed after seeing Poltergeist at age 12.  And I'm fifty-some-odd years old now, so...lasting impressions.)

I'm assuming* that other people are also either exclusionary to their format choices or have a few types that are their thing.  Separating the bundles into format (IF, video, physical, assets) would mean I could buy more of what I actually want, while being able to support creators making things I enjoy.  And hopefully putting a spotlight on creators I may not have found organically.

(* you know what they say about assuming, so maybe speculating is a better term. :D)

Yeah I would agree to separate based on format of the submission, if there are classifications, if there is too little of one format and an overflow, then take the little amount one and distribute it evenlly among the formats that have a lot of it.

Also, will we know in what way we will be contacted whether we are accepted or rejected from the bundle?
