I never played the real card game but the old game on playstation 1 was pretty fun. When you're young playing these games their sinister pay-to-win pyramid scheme nature goes right over your head and many people remain spellbound by them well into their 40s and even 50s it seems. With Yugioh, Pokemon, MtG etc. you're playing the same "game" and having the same fun whether you're playing with a $20 deck or a $20,000 deck. In fact, the more expensive a deck is the less fun the game is made, the end goal's logical conclusion being the desire to reduce the whole affair to a single in-game "turn" in your favor.
One good thing at least is that you have an eye for cards that will hold their value or rarer-still increase it over time you won't end up spending a huge sum of money because you can sell them, but I was never a "competitive" player myself savvy enough to spot that sort of thing so I know I spent a ton on booster packs etc.
