It’s so hard to find remotely good games now… I have hit the point that I don’t even bother looking at anything but paid offline games but even those often have microtransctions. I am glad that you can get a refund most of the time as long as you only used it less than an hour.
I have 4 WaveBirds. I had just started my first job in HS when the GC came out and my friends and I became obsessed with Phantasy Star Online. So being a HS student with nothing really important to spend my paychecks on, I ended up with 4 WaveBirds and the broadband adapter. I almost bought the keyboard controller even. We stopped playing PSO before I did buy it unfortunately but I did later use the broadband adapter and PSO to stream pirated games to my GC though so that was fun.
