This thread brings back memories for sure!
My earliest memory of rhythm gaming was going to Disney World and seeing these two guys playing DDR Disney Mix at Innoventions. I thought I would have been good at it because I play soccer and have fairly quick feet, but alas, we all know no one is good at DDR their first time. In the fall of 2005, I played DDR Extreme 2 with my friend on his PS2 a few times and it was a lot of fun. I started getting the hang of light songs and streams of quarter notes. That Christmas, my parents got me DDR Universe 3 (so surprised other people actually played this game!). I played a lot and started skillboosting a ton, so that by June of 2006 I was close to FCing Sakura on Heavy and I had passed Legend of Max on Heavy (incredibly challenging on a soft/foam pad!). During that time, I saw someone at school playing FFR, so I lurked there a bit until I made an account. I also downloaded Stepmania and got files from bemanistyle/FFR. These days were the good ol' days. Through the rest of 2006 I played more SM than FFR and I got pretty decent at index. However, I really wanted to play all of my files on a pad, so for Christmas my parents got me an 8 panel usb foam pad. Unfortunately, it was either broken or I was retarded (probably the latter) because I could not get this thing to work. That was the beginning of a long hiatus on rhythm games for me. FFR and bemanistyle lost their databases, and I lost interest.
In 2008 I started playing Guitar Hero 2 & 3 (2007 beat the entirety of Super Crazy Guitar Man 2) and I got decent at it. I could never beat TTFAF or Devil Went Down to Georgia, but I had a fun time playing it. Then in late 2008, I quit video games altogether.
I came back to vidya (not as intense) in mid 2010 after I graduated high school, but I didn't have much interest in playing so intently. The computer I played SM on was untouched for two years and this was around when FFR was offline. I would play FFR on the lightdarkness server on occasion to show my friends what it was all about, but I didn't come back until late 2012 when I found out it was back up! I started playing FFR a lot more, downloaded the Tachyon packs by MadMatt, and frequented the forums. I downloaded osu! on my iPod Touch randomly, and decided to look it up online. Sure enough I am here infrequently and I am enjoying it! Although, I'm so used to 4key that anything else is difficult.
