Yeah Tekken has a lot of moves and strings, but they always get boiled down to key situation responses and what is considered safe in competitive play. And oh c'mon, YXR (light medium hard punch), LBA (light medium hard kick). The only time you had to change the way you held the SNES controller was if you wanted to be a total cheese ball with the light jump kick to light crouching kick spam nonsense (lol).Yea, but like most fighters you should know all of them. When I was younger, I knew all the characters. Every one. I would play and learn all of their movesets. It helps in countering if you know the moves and their buttons. As, Jin has a reversal based on certain button combos. If you don't know what animation is tied to what button press, then it's hard to counter a throw, or combo. The reversal game in Tekken isn't as deep as Dead or Alive (which is almost purely based around) but there is certainly an aspect to it.
I'm not nearly as patient as I use to be when it comes to fighters. I just don't have it in me to play them like I use to. Still, I hold a special place in my nerd heart for Tekken. It was the first fighter was actually okay at. Street Fighter was so cruel to me growing up, because the fighter was a 6 button one, and I couldn't wrap my head around the limits of a four button controller and shoulder buttons.
I wouldn't improve in Street Fighter until I got an arcade stick.
