How come some of u actually think this game is expensive? is that a joke? have u seen any of those games that cost u like 199$ in Steam.
All of them have limited content, Duel Links doesn't.
Basically, here is a dialogue discribing what players are screaming of:
Konami: "Welcome to Duel Links! We hope you enjoy "Yu-Gi-Oh! Duel Links".
Player: (after he likes the game) "Wow, this game seems great, I'll play it"
Konami: "In which mode you'd like to play in? This game is free to play but does provide in-app purchases"
Player: "Oh, I'll just play free"
Konami: "Nice, then you will build your deck after 2 or 3 months of playing"
Player: "Really, nah, I'll pay for my decks to enjoy the game now"
Konami: "That is a good choice, here are your decks. Go ahead and beat everyone with your strong deck".
There are some dudes who plainly hate this game (and I actually wonder why bro), it's not time demanding because you don't need the last decks to win. In the last KC CUP the 1st GLOBAL PLACE was playing Amazoness and Vampires. No Koa'ki Meiru and NO Ancient Gears at all, yeah... the game does not force you to buy cards at all, buster blader is pretty OLD by now and it's totally competitive.
Well, you are technically right about that. Any mmo, online rpg has unlimited content. Most of them are free to play, I'd say Duel Links is quite similar.
