I m starting all the way back to the first game, where there is only monsters and spells. The grind is real every ten wins you get something new in addition to the random prize at the end of every duel. You get a rageki with monsters topping at 800 attack. Your 800 attack wins over everything yugi has, and you ll win higher attack monsters. Than you realize Joey gets a red eyes and a thousands dragon vs your beautiful head hunter or flame swordsman fushion, you went from winning ten in a row to being killed as you can only play one card each turn and without regeki or the black hole (prize card), no card in your deck can come close to 2400 attack without a 4 card combo (fushion need one card on field with the second played over the first, equip, field spell). There is no power level system so every good card can instantly go into your deck.
I haven't tried the other games as much, but I know they will include a limit of what cards you can put in and I do look forward to the dungeon dice monster game, and the new experience of some other old games I never played when I was younger.
Thank goodness an era collection before links and hand traps. Also the promo card comes damaged, but I understand by getting a hold of Konami that they will fix it with proof of purchase.
