I'm pretty sure all of these games are wayyyy less complicated than Brawl. Like, immensely. It seems likely the lag is just a result of the nature of the game. And also the result of everyone ever using the online service.Here's a brief list of all the games that have better online than Brawl:
Mario Kart DS(Rarely laggy)
Pokemon D/P(Voice Chat)
Mario Strikers(Not as laggy, leaderboards)
Metroid Prime Hunters(OH MY GOD, someone let Retro do the online for EVERYTHING nintendo related, minimal lag, rankings, voice chats for friends, IT CAME OUT YEARS AGO AND ITS BETTER THAN ANYTHING COMING OUT NOW)
MKWii
(On an unrelated note, while I haven't spent much time online with Hunters, I've heard that the game is cripplingly glitched, so that multiplayer becomes ridiculous against anyone who knows the glitches well.)
Don't get me wrong, though. Lots of things about Brawl's online is lacking. Mostly the utter lack of options. Items always on? Fine. Always two-minute matches? Sure. But the real problem is that you can't choose if you want a free-for-all or a one-on-one. I would venture to guess allowing for a 1v1 match as a choice would go a long way in remedying the lag.
Either way, I wouldn't really blame Sakurai for the state of things. There are a lot of things out of his control, and it'd be oversimplifying matters to say he "didn't want" this or that for whatever reason.
P.S. Not targeting you specifically, Pink Reaper, you just happened to sum up the points I disagreed with well.
