For many Mega Man enthusiasts, there hasn't been much to get excited about since the 16-bit generation (save for the two collections and today). Perhaps this was due to the fact that many of those individuals were Nintendo loyalists and went with the N64 instead of the PSX or Sega Saturn. My being one of those types, I wasn't able to experience the X series on a 32-bit console until about three years after its release when I traded my brother's unused bicycle for my friend's brother's unused Playstation (what a great deal ... for me and my friend). Once I got my greedy mitts on the system, one of the first games I bought was X4. And boy, was it worth the wait.
Everything that made Mega Man X amazing on the SNES was turned up a few notches for the series' 32-bit debut, as the graphics and attention to detail were incredibly impressive. The large bosses were much more mobile and animated than their 16-bit counterparts. Action sequences were more frantic and faster-paced. The entire experience just oozed power. Fully animated cut-scenes (which were new to gamers whose regions didn't receive the re-release of X3) made the experience that much better. And how about that final Sigma battle? To borrow a catch phrase from a very under-rated sitcom: "legendary."
