I already know pokemon. I'm making an active effort to not be into pokemon anymore.
As a kid i wasnt allowed to watch tv or play videogames, so I've been trying to catch up on the childhoods everyone else had.
Trying to get out of MTG, not interested in the Pokemon TCG or the One Piece TCG because their mechanics aren't interesting to me, and there is no amount of money you could pay me to deal with the average Yu-Gi-Oh player. The Digimon TCG seems cool, though.
Play some of Square/Squaresoft's various JRPGs from before the Square Enix merger.
Watch some awesome cartoons that got tragically cancelled before they could finish. (ABC's "SatAM" Sonic the Hedgehog, Pirates of Dark Water... technically Thundercats 2011 is too late for my childhood, but it's the same idea).
Between the two, Flesh and Blood looks like long term would have more staying power. They are currently having international and local events. Looks very cool... And tempting haha. I love TCGs too but it is an investment and time consuming....
I loved both as a kid but Digimon was a much better story. Pokemon was super cheesy and felt like it was just made to sell video games and trading cards.
