Hi, i looked forward to update an old videogame tittle in unity, but can i sell it, or do i need some special permission ?
Nintendo tittles:
Ninja Gaiden I,
Contra
Others Atari Tittles:
Montezuma
Draconus
MsPacman
No.
no?.. but no what =? hehe… can´t I sell ?
you can call them contraa or ninja gayden … no problem ^^
this.
muahahahh… ehm okey thanks 
no. err… thanks … @_@
I’d be cautious about doing it. Don’t use any of the same names, any assets from the game and you’ll probably be good.
My guess is that you’re good as long as you don’t sell it, or somehow become famous for your remake. Other than that you should be safe, I think. :-0
About 20 years ago Acornsoft made Snapper which was a direct Pacman copy and played very well. They had to change the graphics of the ghosts and pacman before they were allowed to re-release it.
the orignal game
after the threat of sueing by Nintendo!
Hm, this is an interesting topic, I was thinking of doing something similar myself:
A remake of the old War of The Worlds PC game from 1998, it was one of the first games to use 3d models, mix of RTS and Turn-Based gameplay, was developed by Rage software (now bust) and published by GT Interactive (don’t know if they’re still around), I was thinking of redoing it using Unity, but setting it in a different time period (late 90s, 100 years after the 1st game), and also adding my own ideas for units, I might not be able to release it, not without asking Jeff Wayne real nicely.
Here’s the intro vid. War of the worlds main intro
It’s completely illegal to remake any games unless they specifically give you permission legally to do so and in writing.
All of those games are actually remade by their owners anyway every couple of years and resold as packages, as xbox live arcade minigames and so on, they would sue you into infinity and beyond and leave your poor broken corpse in a dark ally for use by pirates to feed on.
Just make your own versions with different names, art and levels.
ohhh my goOOOd, i thinking in old games because many of them are really funnier than actual tittles… regarding to what hippocoder said, don´t forget Prince of Persia is a 90`s tittle, from Brunderbund software, and now, there are 4 different Prince of persia but from Ubisoft… i was meaning about that too… how is it?, Brunderbund turns into Ubisoft maybe?.
yeah, i guess this is the better way…
If anyone could just copy and make money off of someone else’s original work, then what’s the point of copyrighting and licensing?
They purchase the franchise / rights to it. This can get pretty complicated, with the original company is wanting to retain some rights or something, like having a say in how the story develops so the company cannot take it too far from what the original author wants, etc…
Buying the rights to pac-man probably isn’t feasible.
Making a game similar to pac-man is feasible, and legal, provided that the game is different enough. If you’re totally determined to know how different it has to be then you would have better results asking around legal websites I would think.
For an example compare the Descent series with the Freespace Descent rip-off. Essentially they took all of the same principles that made the game fun and changed enough to make it their own. Which was basically making punk characters and putting them on bikes instead of spaceships and making everything in triples instead of quads. With no significant naming ties this can’t be considered a remake but the game is extremely similar.
You can’t. You can’t make a game containing original assets by other studios meaning (Graphics, art, textures, sounds) but you can remake the idea. Say a jumping technician going to save his princess. (Mario). However no way the story can be the same too. In the industry what can be copied IMO is the mechanics. Other than that, assets are a NO NO.
Its called intellectual property, or IP. Games are sold to different companies (or the rights) all the time. It doesn’t matter how old it is.
Back in those days they didn’t have a lot of prior legal rulings to stand on, nor would have thought about it much. For example its only relatively recently, the supreme court ruled that a GUI could not be subject to patents.
In any case, pacman is tightly protected 
they do tend to go after people. The tetris crowd are just as active too.
But you know, prince of persia is just a run and platform game. Call it prince of the congo and have him slightly darker with a bigger sword and you might be onto a hit 
Nintendo don’t own the rights, namco does I believe. Just look at how hard companies milk their old titles… you would be in a world of pain trying to clone any pac-anything: The Official Site for PAC-MAN - Video Games & More
I’m curious how much fun the arbitrator would have if somebody actually brought a piece of legal advice from this forum to an arbitration meeting. “Marumaru said it’s totally cool as long as I change the name a little bit.”
hmm, all right, after all, there is a chance to modify a bit an old tittle and simply change the name. of course assets, music are not the same since nintendo or all old games are 2d sprites and unity i´m using 3d… 
, might work…
LMAO.
Don’t take this forum’s advice seriously. You need to see a lawyer if you really intend to infringe upon other’s trademark (the correct legal term). Seriously. You will need it. You cannot just change one or two letter in the name and think you can get away with it. There is something called “confusing similarity” in law speak that basically test if your propose name (trademark) against the registered trademark side by side. If its even recognizably similar that consumer / jury can get confuse by it - you will lose your case.
Of course, you can still argue the accuser’s trademark has become common word (trademark dilution), but chances are its very uncommon to have a registered trademark turn into common word (genericized) and lose its trademark status. (See “Genericized trademark” - eg. Aspirin, Yo-Yo, Videotape, Escalator…etc.)
yes mate, i understand, game´s mechanic is the copyable part, i´m actually thinking in mix mechanics, world map, adventure, but not sounds, story, and graphics… just mechanic…
