I strongly suggest you take a look at CrappyCaptureDevice's video series on Youtube. Brinstar was a fusion of at least three different chambers from the first three Metroid games. The Super Mario World stage combined the first two stages, while using music from yet another stage. Green Greens used a gameplay element from The Great Cave Offensive while adding in the Whispy Woods boss battle. Flat Zone took ideas and scenarios from the Oil Panic, Manhole, and Helmet LCD games. The Pokemon stage comprises many different environments--the concept of a shifting stadium actually comes from the anime. The word you're looking for, Wiseguy, is comprehensive, not generic. To give due representation to a broad series of games, it makes sense to include as many elements as possible.
Not only are your generic vs. specific comments wrong, they are irrelevant. The true question here is, "Since it appears that they have used, in part, an element found in the Icicle Mountain stage in Melee, and since similar stages should be avoided, could the Ice Climbers' stage be reimagined or optimized for this game?" As you have already seen, plenty of ideas for a better Ice Climbers stage have been offered, and we're just amateurs.
Maybe I could have phrased my argument better....
What I was trying (poorly) to say was more or less what you said: that many of the stages in Melee draw inspiration from actual games, not that they are 100% copied from said games. For example, in Great Bay the giant turtle never visits that exact spot - but this is still an aspect of Majora's Mask that serves as a fitting homage. What I meant my "generic" was more along the lines of the Great Temple - which captures the feel of a Zelda game without drawing specific elements from specific games.
Wait... where was I going with this again?
Let me try and unscramble this mess I've created:
In my (humble) opinion, Icicle Moutain mirrored the format and feel of an Ice Climbers level extremely well. More so than most stages, it captured the essence of the game it was trying to represent. Ice Climbers consists almost entirely of jumping up and up from one platform to the next, which is precisely what the player does in Icicle Moutain.
Now, since this concept fits the Ice Climbers so well, it seems only logical (to me) that they would incorporate it in the new Ice Climbers map - if one is being included. However, since this exact stage format is used in Dk's new map it seems unlikely that a second Icicle Moutain-esque map will be included.
Therefore, I would argue that there are three possibilities:
1) The ICs will get an entirely new ICs themed map, as some here have suggested.
2) The ICs will be included without a new map (ala Marth and Roy) and Rumble Falls will replace Icicle Moutain.
3) The Ice Climbers will not return and Rumble Falls will replace Icicle Moutain.
The first possibilty seems to be the most popular here, and it is by no means out of the question. However, I personally don't think any potential Ice Climbers stage could capture the essense of the game as well as Icicle Moutain. Therefore, it is my view that if a IC stage were to be included it would be a reworked version of Icicle moutain. I could be wrong, but That's just the way I see it.
The second outcome is also possible, but since it's very unlikely for a character to be included without a stage I can't see it happening.
That leaves me with door number three. Nothing is set in stone, but I truly think that the demise of Melee's dynamic duo is more likely today than it was yesterday. Keep in mind that it's just one guy's opinion.
It's not really fair to compare Super Mario Bros. to IceClimber.
Fair or not, it's true that conceiving of a new stage is far easier when you have several games to draw inspiration from.
If by "all" you mean two or three out of fifty...
Fine, you got me there. But I think my point is still valid.
Also, the Fire Emblem stage was cut because of time, too. Same with Mach Rider as a PC and Ditto as a Pokeball Pokemon. There are lots of cuts because of time. I don't think time is a factor here. So, Sakurai will keep all the characters he likes. If he likes ICs, they will stay (obviously).
Sakurai will keep all the characters that he thinks are worth keeping. Will that include ICs? Maybe, maybe not.
Time is still a factor. With december fast approaching there are deaslines to meet.
They have some evidence. Sakurai said that he wanted to have some forgotten retro characters. How would he be supporting that by removing them?
He would be supporting retro character by including as many new retro characters as possible. ICs are a great character, but frankly, I'd much rather play as an entirely new retro character.
I don't really see retro characters as guest characters either. I love the retro characters, and I'm glad they're in. In a lot of ways, I feel like they're just as important to Nintendo's success as even Mario. In the early days, games like Balloon Fight, Ice Climber, Clu Clu Land, Kid Icarus, and Punch-Out helped propel Nintendo forward as the leader in video games.
Obviously a plumber saving a princess from a giant turtle has more potential than a man flying over the ocean with two balloons strapped to his back or a hammer-wielding ****** scaling levels of blocks, but they still were important for Nintendo to show its versitility in the gaming industry.
Oh, I'm not disputing the importance of retro characters. I just think that since there are so many worthy retro characters, ICS and G&W should step aside so that two other retro characters can chave a chance to shine. I'd much rather see Balloon Fighter and Little Mac playable in Brawl than ICs and G&W, simply becuase I've already played them to death.
That's just an opinion. Feel free to disagree.
