I don't know about you, but I've loved playing orcs in video games. They always have a great place in fantasy as a fictional humanoid character.
oh yea? i like the nintendo switch.. some of the games are fun
I agree. You can probably play games with orcs on the Nintendo Switch. If you don't have a good idea of what an orc might be or what they look like, you can get the best idea of their conception from the fantasy writer J.R.R. Tolkein, and his work of "The Lord of the Rings," where he shows them as massive, brutish, aggressive, repulsive, and malevolent.
oh yea the lord of the rights is nice
To give you an idea of his orcs, set in his world of Middle Earth, they're shown as, at times, dim-witted, but also crafty, but usually miserable, spreading hate for everyone, even themselves and their own masters. They're driven by fear and greed. Their only desire is to hurt and destroy. Tolkein's orcs don't really have many redeemable qualities, truthfully.
what about that book/show the game of thrones? some good orcs ?
Not so much in the Game of Thrones, but you will find them in other areas like the role-playing/strategy game of Dungeons & Dragons, as well as Warhammer, and also Warcraft, all which have their own universes. So, you can see the popularity.
the way you explain it i can see the difference 
Well, there is a difference, truly. In Warcraft, for example, orcs can be good, and they have very unique motivations. But generally they do follow Tolkien's model, even though they can be portrayed differently at times. Most of these portrayals do include a human shape, but with bowed legs and long arms of different sizes.
