The convention/Expo in question is Midwest Gaming Classic. From a gaming standpoint, this event has video games, Air hockey, laser tag, arcade games, pinball, computer games, table top gaming, chess, trade card gaming such as Magic the gathering as an example, speed cubing aka solve Rubik's cube quickly, and live action rpgs aka Dungeons and Dragons.
@Agent H, this gaming event in not a corporate event and that means nothing on Nintendo Switch 2 although new pinball games do first show up here. The event does have demos of upcoming games, but no upcoming games on modern games systems unless it something like an Atari 7800+.
Midwest gaming Classic for video games is anywhere from classic video games to modern gaming.
