Just got back from another retro gaming convention. I've got to say, these things are on a steady decline. Maybe it's just me, but I've noticed less and less of a selection of games at these places, which is telling given than many of the vendors come from near and far to attend. The selection is just at a point where a lot of those big ticket, sought after titles, common or not, just aren't there much anymore. I kept overhearing people in search of those same high profile titles that I was hunting out more than 10 years ago. Folks still want to find that stuff today, and collect it.
Luckily I'm no longer looking for those sorts of games, as I have most of them. I guess that's the point, they've been put into collections. I'm mostly scoping out oddities and obscure hidden gems which fit into the category of not too rare, or valuable. I found a handful, not a lot.
Anyhow, I think the enthusiasm for these events is waning. A lot of collectors fighting against one another for what little is left in stock, I think it's indicative of the state of game collecting. Supply running low, while yet even more people become enticed every day to jump into the hobby. The level of collecting is outgrowing the supply from golden age of physical media, and yet they're desperate to stop producing physical media with today's games.
