The arcade disk was an arcade port. It had a loose, but not lk lk to anything, combo system. Some characters had different combos (such as Akira). Tardy counters were free, but you can’t punish weak attacks (which generally meant that most matches were exchanges of lk).
There were parts I liked about the game, and many that I did not. I loved Akira’s combo system. The throw system was also nice, as well as the non-launcher air combos, extremely well-implemented dash. Unfortunately, the lk spam made for boring matches – a single lk that hits meant 50% off at the miniumum, more against characters like Sakura. Air fireball was retarded. Wile you could dodge it, several character could keep you at bay until time ran out, which, again, made for seriously boring matces.
The EVO disk had a different, very strict combo system – I don’t think there’s a single character with lk lk combos but still kept theire lp lp combos. However, since lp could be crouched, it meant no more spamming weak attacks.
