I will vote Yes for "2. Allow pack-in games from games or game packs", as this gives users the most choice.
(Strike-out text on this post made only to keep this thread on topic.)
I also believe pack-in games, included with hardware should be allowed their own entry, under the game category.
People who don't like this type of entry (pack-in games from games or game packs) could just ignore them and not add them to "their" collections.
I buy mainly unboxed, used games and used items, I don't like being to be forced to add things I don't own into my online collection such as piece of hardware as a box set of games, just to be able to add the packed in game. Why should I be forced to add the hardware box set I don't own to my collection, and then put a note on that I don't own the hardware box set.
I understand some users only collect fully boxed 100% complete items and that's terrific for them.
However, I think that VGCollect should be as flexible as possible and allow users who don't collect fully boxed 100% complete items to easily track the items they own. I would like the option to show a picture of just the pack-in game if that is all I own, I could do this if the pack-in game was allowed to have its own stand alone entry.
We have entries titled like "6 in 1 Game Pack", with the six games on 6 different 3.5" discs, each just labeled with the name of the game, but not "6 in 1 Game Pack", as it is now it is very hard to track these type of games in the database. Sometimes I don't have the box, or all the games, but I would like to be able to track the games that I do own.
Being flexible, and allowing diverse types of game game collectors, to make use of the site, seems to be the proper thing and most inclusive thing to do.
