Twenty years later, Street Fighter EX2 Plus is having a renaissance... Go figure. The EX series was tremendously popular in its day, by nature of the game being 3D- But EX2 came a little late and stood shoulder to shoulder with some serious competition. If you were around back then, you probably put your tokens into Tekken 3 instead.
With Playstation games slowly making their way to Fightcade, EX2+ is finally getting a second chance. It's electrifying! But for all the good DuckstationGGPO brings to the EX Series, there are differences. Remember these are still ports. The PS1 is not a Dreamcast: "Arcade Perfect" just isn't in the cards for EX2+ yet.
Street Fighter EX and its sequels ran on versions of Sony's ZN Board. EX and EX+ were on the ZN-1, while EX2 and EX2+ were on the ZN-2. Both of these boards are essentially suped up Playstations. That's good! Lots of arcade games received conversions for the home. In the transition, however, there were cuts. EX2's ports have compromised polycounts, new music, and slowdown that differs from the arcade.
EX2+ on the Playstation isn't a bad looking game, and I personally prefer the CD audio- But it bears mention that netplay might change the standard for events in the future. Sony ZN boards are not nearly as revered or documented as Capcom's CP System. This hardware is gonna die someday... If you go to a tournament for EX2+, expect variance.
