I never personally attended but the fact that we don't have E3 anymore angers me. They literally used COVID as an excuse to shutter it. Too many people used COVID to do away with fun live events because they wanted an excuse to be lazy. Another great example of this is RuneFest for RuneScape fans: EVERYONE who ever went, they all said the same thing, that RuneFest is a blast and a great way for fans to not only meet each other, but also to meet the developers and enjoy the hype of an early presentation of upcoming content. But nope, because of the pAnDeMiC, even three years later, we still haven't had a single RuneFest.
In general, it's a massive joke. Do I think E3 was perfect? Not even by a long shot, but now we have all of these AAA publishers and developers hopping on the "Direct" bandwagon that Nintendo began, choosing a scripted and pre-taped presentation of highly edited gameplay, rather than having that live developer-to-audience interaction or the live demos that you could often get at E3. Nevermind the fact that it just further reduces the socialization aspect in this industry. We already have a problem with that where people choose short-form communication on centralized services like Discord or Reddit rather than using in-game chat for online games, or forums for other types of games (which is why I still do appreciate the GOG forums overall).
Anyways, rant done. Before COVID, in spite of all of the issues, I actually had a lot of hope for the future of the industry. After COVID gave these publishers an excuse to be lazy, anti-social and even more phony, I've lost most of my hope and hype for the industry. Of course, that's not the only reason; part of it has to do with things like Microsoft monopolizing by buying up a billion studios and publishers. However, the death of gaming conventions in favor of "Direct"s really angers me in a way I can't quite explain.
