im not upset you just seem to think using the word fucking and capital letters = upset
That's because "fucking" is what is called an
intensive, which is to say, a word which modifies the intensity of the statement being made. The use of any intensive will lead to anyone reading what you're writing to assume you are feeling somewhat passionate about what you're saying. Capital letters do the same. If you're not passionately happy or sad, it's pretty much a given to most people that you're angry if you say "fucking" and capitalize your words. Don't blame other people for not understanding how you use the language if you use don't use it right!
Anyway, the fact that Giga Bowser is playable (even for only short periods of time) pretty much guarantees that there's no limitation in the engine preventing large playable characters. The only question is one of balance, and being larger has an
automatic handycap in the form of a larger hit box, and the fact that Jigglypuff can
mess you up if you're playing a large character. A large character with stats comparable to a regular sized character is, if anything, sort of
weaker than a normal sized character with those stats, albeit with a better range on melee attacks.
And all of that's even assuming they kept him on the "OMG, HUGE LIEK XBOX"* size that so many of you are insisting on....which I don't really think is necessary. And Severus already covered all the issues about what sorts of moves he would have and such, and how he would operate on a normal-Bowser-scale.
Basically, none of you anti-Ridley people have come up with points are really clenchers. I mean they may be enough for you, and that's fine, but you're not going to prove anything to people who think he's a possibility with them.
* - Note: while, as I said earlier, capital letter often work as an intensive, when used with intentional spelling mistakes and making references to stupid internet memes, they operate more as a form of mockery than intensification.
