I still have to tackle a few dozen more info forms from publishers — a delay caused by me focusing solely on Gen Con 2018 until that show was underway — and hundreds more games will be announced between now and mid-October when I finally stop updating the preview, but this batch of 222 listings will get you started for now. If you want to know how to use the preview to prioritize titles and make a personal shopping list/wishlist, head to this long explanation of the GeekPreview format from mid-2017.
If you are a publisher who did not receive an info request form from me, please Geekmail me or email me at the address listed in the BGG News header, and I'll send it your way.
One note for publishers related to activities that happened in the Gen Con 2018 Preview: Please do not use contests or giveaways to encourage people to thumb items on the SPIEL '18 Preview. Doing so violates the terms of service for use of BGG. Encourage people to check out the games you have on the preview, possibly even suggesting that they thumb games they're interested in playing or owning, but don't tie such suggestions to a potential reward for doing so.
Ten more weeks of SPIEL '18 Preview updates commence now, with a video preview of one such SPIEL '18 release coming on Tuesday, August 7. Onward!
