User complains about Street Fighter 4's net code, Seth responds

[Paraphrased] How come the net code in Street Fighter 4 sucks so bad? I like the game, but you guys aren't supporting it with new stuff often enough, that's disrespecting the community — it's been 6 months since it was released. Bethesda released tons of DLC for Fallout 3 and that took far more work to do.

HD Remix had really good net code, so why didn't SF4 use GGPO like HDR did?

Seth: You like the game, you like the features, you just want more of them and better versions of what's there. That's very natural, but the fact that SFIV has totally revived the fighting scene, had the biggest tournaments of all time around the world (the biggest of which are directly supported by Capcom) is just not "disrespecting the community," even if you would like to have more new hats for Ryu.

As you point out, it's only been 6 months since the game came out. It might seem like a new Fallout expansion is "far more work" than new SFIV features. I am impressed by the Fallout 3 DLC support, but I would say that the work involved with a robust expansion to a carefully balanced fighting game is AT LEAST as difficult as that kind of effort. It's also a very different kind of work, of course, but all of this is beside the point.

As to your actual questions, SFIV and SF HD Remix are built on totally different engines, and the same netcode solutions are not always equally viable in different games. Beyond the engine, the input system in SFIV is also notably different than the more traditional SF2 inputs on HD Remix (both on and offline), so the SFIV netcode was built with that in mind. I'm glad to hear you like HD Remix code at least, and I think that if anything, that's a pretty good sign that as a company we're very committed to an online experience that does the most justice to the offline fighting.
