Prior to Melee:
Who remembers Mr. Game & Watch? Who actually played Game & Watch? He is Japan-only. R.O.B. is international. A lot of people around the world have actually played Gyromite and Stack-Up. People still remember the robot before the Internet became commonplace and long before the Internet and Smash 64 educated people about Mr. Game & Watch. Mr. Game & Watch is forgettable. R.O.B. is not. If Mr. Game & Watch shows up in Smash, many people would be wondering who the hell is he and why is he in the game instead of someone more famous like R.O.B. Mr. Game and Watch doesn't have the star power or the name brand like the Ice Climbers, Balloon Fighter, and R.O.B. do.
I may not be ViewtifulGene, but I think he would be proud. (BTW, Sheriff isn't Japan-only if you actually did your research. Also, the Ice Climbers were hardly popular and came from a crappy game, and still got in.)
Game & Watch gams throughout the 1980's weren't Japan-only. Game & Watch Gallery 1-3 from 1997 to 1999. Mr. Game & Watch were in those games. Do your homework before posting misinformation on the Internet.
No one cared about Ice Climber, Balloon Fight, etc. prior to Melee. The only reason the Balloon Fighter is so heavily requested these days is because people still believe that the Balloon Fighter was planed to be in Melee. This is the power of misinformation. The only reason Ice Climbers got in over Balloon Fighter, Bubbles, Excitebike, and Urban Champion was because:
- they wouldn't be useless even if they lost their gimmick (Balloon Fighter becoming useless if his balloons popped compared to Popo still useful after losing Nana)
- they can fight (Ice Climbers can fight but Bubbles couldn't - how can she fight if she can't even stop moving around?)
- they don't need stages modified to accomodate them (Ice Climbers don't need ramps installed all over the stage in order to jump like the Excitebiker would)
- they are very interesting (Ice Climbers fighting with ice powers and mallets more interesting compared to Urban Champion's boring and sluggish punches)
I didn't make up these reasons. They came straight from Sakurai on the Melee Dojo.
Who has the potential to be very interesting? A hunting dog that fights with ducks, clay pigeons, and the NES Zapper... or a cowboy who shoots around with a revolver gun (Sheriff or Wild Gunman)?
