By complete and utter chance, Sakurai made a very deep game excellent for both casual and competitive play, and while every forum everywhere (regardless of the game in question) seems to think that "tourneyfags" generally deem themselves superior to casuals and want to enforce their own ruleset to everyone, the opposite is way more often true. As you can see.
I was no competitive Smash player myself (I just preferred no items etc), and while Sakurai has the full right to do what he wants with his series, I say he's shot himself in the foot by shafting a small but very devoted* playerbase (by more than just the tripping, really). I don't understand why people genuinely like tripping, or critical hits in Team Fortress 2, but I'm fine with them as long as they can be turned off for those that like playing the game the way they want.
As for being on-topic, no, I don't like being randomly screwed or blessed or stupidly interrupted by a factor I have in no way contributed to, seeing as I'm not so bent on winning that I'm willing to do it through such a mechanic. Remember, competitive players don't dislike tripping because they might lose. It's disliked because it might keep the best man from winning in an unneededly, controllable way (unlike wind in Golf). When losing repeatedly, a 'tourneyfag' will work on his skill. Not hope for a hammer next time. The occasional elitist prick does not have a competitive mindset.
As for the argument of taking party games too seriously, well, there's no game quite like Smash.
*If you hadn't noticed, Melee's metagame has been running strong throughout its seven years and showed no sign of stagnating. Heck, now people are making a hack for Brawl to optimise it for competitive play whilst preserving its well-received additions. No software developer kit or anything, just a third party hack tool bricked by each Wii update.
Also, first post in how long? Half a year? xP
