I'm also a fan, but I only play it in "phases". I play it a lot for some time, then I don't play it at all for a long time, then I get back into it and play it a lot again for some time. I hate KONAMI for net making any good Yu-Gi-Oh! games, though. Even when they do, they mess them up in the west. They just recently released Duel Carnival in Europe, but they cut over 50% of its content out. They also just recently started a new online game, but that one is "meh" as well. If you want to play the game, you pretty much just have DevPro, which is great for its implementation of the card game itself and even is free, but doesn't have much else to offer. I kinda liked the official games with their stories, NPCs etc.
Anyways, I just yesterday spontaneously bought the newest starter deck of the TCG, Spacetime Showdown. I usually buy the first starter deck of each generation, just to give the new card types a try. Pendulum monsters seem pretty cool, but the starter deck only has two of them, which makes them a bit less useful (since you need both of them on the field to use pendulum summon first place). I also don't know if I could fit them in my current deck. I could at least give it a try. Still have to look more at each individual card from the starter deck, though.
Feel free to visit my website/blog - it's updated rarely, but it looks pretty cool!
