Cool, let's give this Smash Timeline a try.
64:
Age 10
I never owned it, the N64 game I had at the time was Mario Kart 64, but my cousin introduced it to me, and I've been hooked on Smash ever since. It was all we would play when I came over, but he and his two younger sisters would kick my butt,
and the youngest sister who was six at the time killed me with Kirby, every single time I still have nightmares. My love for the game is pretty much incurable by now. At the time I only knew these four characters (but I only played a little DK maybe I should get Tropical Freeze and change that)
Melee:
Age: 11
By then, even if I didn't play much of the other series, I at least knew about them, I was definitely excited to see more Pokémon especially Gen 2 and Mewtwo(since I'm basically playing all the main games released). I instantly gravitated to Sheik (cause I like Ninjas/Ninja-esque characters), Marth, and Roy (cause I like Swordfighter (Soul Edge/Soul Calibur is to blame for that)), and the Ice Climbers cause they were so unique. At this time I was playing Smash with my classmates at least this time I actually stood a chance.
Brawl:
Age: 17
Probably the most agonizing wait for a game that I ever experienced. Except for Pit, Zamus, and Lucas, I knew all the characters in the game, and I held the (somewhat) unpopular opinion of loving Subspace Emissary. The character I was most hype for was Lucario, my favorite Pokémon, I just wished his speed and attacks were faster.
Smash 4:
Age: 24
Pretty much knew most of the characters and the series they came from. I still remember how happy I was that my picks made it in (Lucina, Palutena, and Corrin), and that the Smash Ballot was a real thing. It was around this time I started coming onto Smashboards to learn about the game but I was mostly a lurker.
Ultimate:
Age: 28
Actually the most active I've been on Smashboards since... ever it really makes the wait for Ultimate more tolerable. I really appreciate the different people I get to talk to, and all the points you all bring up. If it wasn't for you all and this place introducing me to characters I never would thought of as potential newcomers, my Wishlist would be just Lyn, Krystal, Amaterasu, Shantae, and Sora.
So thanks everyone.
Edit: 17 for Brawl, I swear I'm not the ultimate life form
