Pretty much 100% untrue.
I read through this entire forum last night and found a lot of insightful stuff. I've picked up Game & Watch as a secondary, but I've been playing him for the whole of a year, maybe.
Some of my input on these match-ups.
I find the Sheik match-up kind of fun, partially from being a Sheik main myself. Ducking needles always seems to be the way to go with me. I'm garbage at lightshielding, so I typically will play a lot more defensive and not let Sheik wail away at my shield until she gets a hit into a adaoijdoaij combo. I really love approaching with Dair and it throws off shieldgrabs really badly. Most Sheiks I play against often start their combos out of a shieldgrab, and Dair while kinda floating in the air with it makes it hard to do against. Dtilt isn't bad either, if you can read a grab approach. I see some G&W that will just toss out SHFFL Fairs, but that's the best way to get shieldgrabbed imo. Playing defensively doesn't hurt in this match-up because Sheik is a shark, and everything she can do to punish an overly offensive G&W will destroy him. Lowering Sheik to your tempo can do wonders sometimes.
Peach.. I only play against one Peach player, but he's not that bad. The only thing I've read here that he doesn't really do well is predict my Dairs and try to counter with Usmash. That might be why I basically treat this match-up as "Fulljump Dair heaven." Hovering Dair shuts down her ability to use Dsmash, which G&W shield and practically his lightshield can't stand up to. It beats out FC Nair and often FC Uair. If you can hammer it out, Dair can outprioritize turnips as well. I praise Dair for being really amazing in most cases, but that's just me. I find Nair to be really useful as well. Peach just floating back to the stage can have a hard time avoiding the chute when she can't really fire any FC aerials to get through it. I don't grab Peach a lot from personal experience with Sheik/Peach, where I grab and she spotdodges into a Dsmash. Ftilt isn't that bad for ground options, but I keep most of this battle in the air for G&W.
I absolutely hate and get wrecked by the Marth match-up, and for a couple reasons. I think the biggest reason is the fact that I don't cook bacon. Ever. I can't think of the last time I seriously used G&W's B. A big mistake on my part, and it typically causes me to go overly headfirst into some matches. This is one of those. I find that Game & Watch
cannot freely approach Marth and his giant steel ***stick. Very rarely can I manage to connect with Fair, practically the only thing that can outrange his Fsmash, and usually only if I can throw it out early enough to predict Fsmash, when Marth moves his head/body forward before doing the attack. That's about as open of an opportunity as I'll get, most of the time. A ****load of defensive play, very few open opportunities, and a lot of prediction necessary to punish Marth and start comboing him. Marth does mean things to G&W from the start, but from reading some advice on this thread, this match-up feels a little more doable.
The Falcon match-up feels pretty even in my mind, but the only good Falcon I play is an absolute beast. Obscenely fast, and prefaces almost everything he does with a dashdance. One hit/grab, then I start over from the next stock. The same can typically apply to G&W, it's just really hard to find an opening in such a fast character. Grab/Dtilt, then do stuff. Most G&W players know what to use in this match-up, but I'm more interested in the way to approach a crazy disco fiend that's dash dancing all over the place, waiting for me to whiff an aerial and then engage kill mode. I guess cooking bacon would do the trick, maybe I should start doing that. xD
I don't think I've ever done G&W/Ganondorf, but I can only imagine it's like the Falcon match-up, with a lot less moves necessary on Ganondorf's part to face**** G&W, and maybe less 0-to-death comboing from G&W due to Ganondorf's not-so-fastfallerness. An easy recovery to gimp, but I don't know this match to be factual on anything.
I don't find Jigglypuff to be a fun match-up for any character. Fair and Bair do wonders for this match, and I'll have to try out jab into grab. I never was able to get the timing down on it, and usually messed it up. I have some work to do with G&W as a whole. Other than that, maybe Ftilt to poke away Bairs? I dunno. Puff is total butts, and when shielding can't be an applicable option, things get tougher. Jiggs is my second least favorite character to play against, but this match-up is really doable. Maybe approaching with Nair and stuff? Jigglypuff's shield is so ohjesus-big, shieldgrabbing is pretty easy for her. I dunno what to do concretely, a lot of this match feels like "look at where puff is and do stuff." >_>
Never played ICs, I would probably go Dair-festing. Probably a bad idea, but I don't play many Ice Climbers. Take it for what it is.
Samus, Luigi, DK, Doc, Mario, Young Link, Link and Bowser are all other matchups I haven't really come across. Luigi is a ***** to fight with some characters because of mega-nair-madness. Link's spin attack could hurt a little if it got the spike. Don't know a gigantic amount of match-ups, but oh well.
My one friend is a Roy main, and I personally have fun with this match. Dtilt is super good on both ends, and both characters combo to the max out of it. Good spacing is kinda necessary. Roy's fair is kinda big and can push away a lot of G&W's aerial approaches, save maybe Nair, but throwing out Nairs can lead to shieldgrabs, which are equally bad to let Roy have. Match summary for either side, really: Dtilt, do stuff, mad edgeguarding. I need to get better at sweetspotting the ledge with G&W's sweet magnet hands, 'cause Flare Blade pounds G&W into oblivion for edgeguarding. :|
Spacies... love playing Falco, hate playing Fox. I could type a big paragraph for both of them and what I like to do, and what happens as a result, but I've said a lot for now and both characters have been covered numerous times.
I'm not that great of a G&W player, but I've got a lot to say from what I've seen. I'm trying to get matches of myself uploaded that were pretty good, but technology is being uncooperative.
Just thought I'd contribute a bit to this thread, it was very insightful.
