Yup, and because of that, I'm at this standpoint:
"6th Ranger Keys Missing"- KibaRanger, GokaiChristmas (have a guy willing to sell me his)
"Extra Hero Keys Missing"- Signalman, Rio/Mele
Other Keys I want- GokaiPink, MagiRed, a Kakuranger Key (same guy willing to sell me his), PuToTyra (coturos is sending me his), TaJaDor (to make into Super TaToBa, same guy is selling me his) and SaGoZo (to mod into BuraKaWani)
Oddly enough, I never ended up spending much cash on my Yugioh affliciton. I either had a cool family member go "Hey... so, yugioh... -hands a premade deck-." Or, "So, Doctormaki... I no longer wish to play yugioh, have these cards." "Kay...." =P Soooo.
When you're 8-14 years old in it's country of origin, Yu-Gi-Oh over takes your judgement. Same with Digimon. Was a huge fan as a little kid, but my last year I could've gotten a Kabuto Belt or a Den-O Belt, but Yu-Gi-Oh cards took my judgement away. Kabuto- Bought a Digivice Burst. Den-O: Spent 5000 yen to get 10 cards, 2 the rare English Change of Heart and Maha Vailo. Did snag my DenGasher before I left though
Go for it. Ironically, I think Ryuki was one of the first KR series I was aware of back when I lived in Japan and even was gonna buy the Ryuki Survive-Dragranzer set, but little me was more concerned with Yu-Gi-Oh cards
