polysquirrel: Nice initiative. I have two qestions though:
1. Did the capacity of DVDs increase while I wasn't looking? Modern games would surely require as many discs as you could find floppies in a box from the 90s?
2. What's the difference between a 'Steam cover' and 'GOG' cover?
1) Early on most games GOG offered would fit on a DVD. Sometime several games could be backed up on the same DVD. As game size increased you could backup to a dual layer DVD or a Bluray disk. Eventually, with the less expensive USB/Hard Drives it became more efficient to use external drives for backups. I make/get covers (for years now) to store with each game install files on external drives to have a copy of the original game cover image and the max amount of game info possible for the stored game. Haven't back up on DVD's for several years. The game covers, for me, are simply an easy way to store some game data with each game . . for future reference.
2) Two separate companies offering games with both sometime offering the same games. I only made covers for GOG and ignored Steam releases since I did not have an account with them. Each company would display game data with different images/info. Steam covers will often have different cover images/info. I always used the original or as close as I could get to it or , , , if not available . . . used the GOG game card image to create the cover.
Sometimes there would be covers available for one company that was not created for the other. Community members would use available covers or the one they preferred due to design. My covers always have the GOG logo and info while those making covers for Steam release will usually have Steam logo. It really doesn't matter unless you simply have to have a cover designed for a specific company. There are many differences between the two companies with many avid fans of both or one company in particular.
