If the Ambassador games could receive improvements, and not just adding local multiplayer and crap like that, here's some thoughts as to how each could be improved.
All of the black box titles (Balloon Fight, Donkey Kong Jr., Ice Climber, Wrecking Crew, Super Mario Bros.) are all largely high-score based arcade style games. Well, Mario not so much, but playing for high score could entice players to get through all 32 stages instead of warp-zoning to the end. All of these games could benefit from having a list of high scores, possibly even online leaderboards for friends and worldwide. Yoshi could benefit from this as well.
Wrecking Crew could have a more user friendly and fleshed out stage programmer, kinda like how it works on Excitebike 3D. The Vs mode would be a nice addition as well, since the competitive aspects sound really fun.
I can't touch on Metroid, all I can say is they should have used Zero Mission as a GBA title instead.
The Zelda games could benefit from some graphical updates and added depth to the stories. Metroid Zero Mission is a good template to use for this... Make the games more fleshed out, add some extra content to the end of it. Imagine defeating Ganon at the end of the original game, but include some content that further ties it in with Zelda II, and create some save spots for Zelda II... Maybe get rid of the 3 lives thing and replace all the extra lives with some other powerup or something.
And Golf? Just apologize for this piece of crap and give us something fun instead. There's very few sports games that are worth venturing into the past for, and this is certainly not one of them. Matter of fact, the only one that comes to mind is Konami's Blades of Steel.
strongo9 posted... They're ports, why would you expect some of those changes?
They're supposed to release updated versions of the games later on anyways when they hit the eShop, so why not? And it's not fair to say I expect them, I just think it would be a great step in the right direction.
