Ah the original Paper Mario. I have super fond memories of this one. I remember when I first saw this at the store my family would go to to rent games. I ended up renting this for so long until I finally beat it, which I remember was on New Years, super fitting really.
Given that the Mario RPGs are one of my favorite series and that this was the first one I played, this game had a really huge impact on me. I remember it was the first game in which I actually got absorbed into its world, and spent hours just exploring around, talking to NPCs, and exploring everything I could.
It was also the first game in which I loved its music so much, I started listening to it even when I wasn't playing it, which began my love for video game music. I loved the mechanics and systems as well. I remember the only RPGs I'd played to this point were Pokemon and Golden Sun, and the idea of action commands kind of blew my mind as a kid.
Looking back, I always loved the way that this game had a deep world and story, yet remained faithful to the typical Mario characters and lore. Where other Mario RPGs liked to leave the Mushroom Kingdom and makes the characters more humorous than they typically are, Paper Mario kept them to their components, while also expanding them with some wonderful insight to shed more light on them. I remember loving it when I found Luigi's diary and got to learn about him and what he does while Mario is away. Peach's segments were also fantastic to spice things up and shed light on what she does while captured, and even Bowser had some great moments when learning more of why he stole the Star Rod and what he and his minions were up to. I really enjoyed the Mushroom Kingdom as well with all its various Toad residents and their fun stories, and I think Paper Mario has my favorite take on the Mario world and its characters, and is a large reason why nowadays I still love the Mario world and its inhabitants, and can't get enough of them.
It's also where my love of Shy Guys came from, and overall, I love this game, and it's always a joy to revisit. Also love all its later installments, even Super and Sticker Star. Can't wait to see the new one on Wii U, but the original will always be special for me.
