It’s less to do with people not liking tournaments now, and more to do with general activity being a lot lower than it was back then. The Showdown server was also a lot more active years ago.
Back then, all of this was achieved without any advertising (so to speak) except for the normal meta thread going up. In reality, the biggest factor to getting tournaments back up again is getting this entire site back up again. I have more discussion threads coming that will relate to this.
