I certainly play with the Unlimited format. I don't know, I can't find the pleasure in the Nintendo-on cards with few exceptions: Aqua/Magma, Team Rocket Returns, FR/LG, Hidden Legends. At the time I was still in (03-04), the trainer engine was difficult for me, as it was Supporters, Supporters, Supporters or flip-dependent/not with the cost. I know it's changed considerably since then and I'm liking the D/P engine, so I dunno.
Don't assume everyone plays broken, as I've seen some interesting range. And I've also seen my share of Rain Dance, Sneasel/Slowking, etc. I usually do a good job dealing with them, usually. But I certainly get why Nintendo doesn't do Unlimited, for you need to spend to get the right Modified. I personally don't care for it, but whatever.
I know Nintendo didn't do Unlimited in Origins in 06, and I didn't bother to check this year. Bah.
I thought Destiny was it, but I did enjoy the e-sets (loved Aquapolis/Skyridge). I'm just an old gamer, so take my musings with a grain of salt. Heh.
