Good point. Ambiguity isn't your friend here.

I threw a LAN party or two back in college (faculty sponsored gaming club). We actually got Bawls Energy and some now-defunct PC peripheral companies to sponsor. I designed and hung posters, put an ad in the student paper, did some word-of-mouth adverts in classes.

The first event had what I thought at the time was good turnout of about 30 people. Most people were OK with mainstream LAN multiplayer games of the time, but there is always that one dude who wants to play Hello Kitty Island Adventure or whatever.

In other words, maybe be somewhat specific and name games that are likely to be played.

I just mostly brought party games with me since it's the first time. Like codenames, Uno flip, flip 7, coup, fuse, and also some decks of cards and a cribbage board in case anybody older showed up. As far as video games, pretty much same with some jackbox games, packman dx+, but if someone wanted to they could play fortnite or rocket league I put a bunch of games on there. I figured I would let the players set the tone for what they wanted to play and we would just provide the space and let it develop it's own culture over time. I did have the idea to have themes like spooky games for the month of October and like I said maybe have a tournament once a month or something like that.

I agree this looks a bit vague to what this is. It needs some more text on the side or bottom to describe what this even actually is, maybe even photography from places happened before. To me flyers make sense, if its already widely known and this is just a reminder to when and where to come, not why or what it is. And the big Bring your Own! sounds like its a must, because the "or" is very small compared to it that one may miss the connection.

Ideally there is a website for people to visit, maybe even with a QR code to scan.
