Instead of wasting that work, though, I'm sharing it with you now and inviting you to check out the Game Market website, submit listings for games to the BGG database, then post a comment about those submissions here. I'll approve those games and add them to this preview, along with other games that I submit or run across myself. If nothing else, maybe we can find titles that you'd like to see in the BGG store later.
These previews I create tend to have less than 10% of the titles that will debut at TGM due to language restrictions on my part, but it's better than nothing and at a minimum a window into what's happening on what I feel is the most exciting part of the game industry. (I think I find JP games exciting mostly because I don't know what to expect. Many of the designers seem driven solely by a desire to create, without regard for whether or not something is saleable. They did the thing, and now they're presenting it to whoever might be curious enough to check out what they've done.)
In any case, here's the Tokyo Game Market • December 2017 Preview.
