I cant believe you like 358/2 days!!! I couldnt get past the fight with the sky beast on neverland. Also, KH RE:CHAIN OF MEMORIES WAS SOOOO GOOD(Vexen was a trash boss)!!!My older sister got me into the series back in 2007. I started somewhat late into the series. I wouldn't truly love the franchise until later.
I loved Kingdom Hearts 1 and instantly viewed it as one of the best PS2 games of all time. I liked KH2 despite my many nitpicks with it's story, presentation, and characters. I tried playing Re:Chain of Memories but failed horribly at the card system and just watched the cutscenes on Youtube. Really good story. After that I took a mini break from the series.
When 358/2 Days came out in 2009 I wasn't that interested at first. I played it in 2010, and it was the first game since KH1 where I was in love with everything. It solidified KH becoming my favorite gaming series. Birth By Sleep was next, I had lots of fun with it but hurt my hands with the PSP button mashing. I'll never forget playing the game at my college while waiting for my next class. This was the last KH game I got to play for awhile though because I didn't have a 3DS for Dream Drop Distance.
Watched the ReCoded and DDD cutscenes online around 2012. Then took big hiatus until 2018's Frozen trailer. Been back in the series full time ever since, and collected many of the games, books, hats, and other goodies. And that's like the short version of my entire history with this series.
