Well, I would often walk up and down the aisles in previous years, but with so many booths and limited time, I would usually just browse as I walked by. If something maybe kinda looked interesting, I might have spent a minute there, but if it didn't catch my interest by then I was off browsing again.
In 2021, with so many fewer booths and more time to kill, I had time to really take a closer look at things I was kinda sorta interested in. It led me to take a few risks, some of which admittedly didn't pan out (got a few game books that were interesting reads and cool-sounding settings, but whose rules I didn't care for to one degree or another). But I found enough games that were cool in both settings and rules to make up for those.
