Actually, the YGO kids were fine to me, as it was more the adults that were obnoxious (particularly because I played Pokemon TCG).
I'll throw this observation out there: In Pokemon, Magic, et al., any deck can essentially win. Yes, it can be difficult in certain cases, but it isn't impossible. There are many times I thought I won, and I lost, and there are times where I should have lost, but didn't. The rest is on the mechanics, to make sure you don't screw your opponent over too much.
YGO is completely different, because unless your first few turns can have you win, you might as well forget it. Not to mention, every card has a counter and be applied almost instantly during your turn, which makes things additionally difficult. It's a different game and different rules, but the formula is so intense.
And I've noticed, you can't have silly decks unless you really know what you're doing. I tried a silly Team Rocket themed deck in YGO, and I got mocked, because I didn't have the right counters or had strong enough Monsters (all were Flip-driven and a few powerful standards).
In the end, I stopped YGO, as it was so joyless and I had no passion.
And yes, there is mass confusion because UD and Konami do keep changing the rules and the banlists. What's a player to do?
And DonRoyale is right about the lack of originality, which is why I stopped with Pokemon, as well.
It was a good learning experience, mind you, but I can't say I had much fun. I was second place in a tour, and walked away. I almost would have won, if the odds were in my favor (I had Gumo and bad flips).
