Lego (trademarked in capitals as LEGO) is a toy manufacturer from Denmark. Its main products are popular building bricks. There have been many licensed games about LEGO products, the first one, LEGO Island, being released in 1997 only for PCs. However, most games have been released for Nintendo consoles, too, all of which can be seen below.
Lego v. Nintendo
In the late sixties, Nintendo developed blatant copies of LEGO blocks called N&B Blocks which, while similar, were slightly unique in that many of the pieces were round instead of square. In commercials that Nintendo aired on television, they compared the two products. In one commercial, a child is building a rocket ship with what appears to be LEGO pieces (the commercial never explains which brand), while another is building a rocket with N&B blocks. The N&B Block version ends up looking much better due to the circular pieces, whereas the LEGO one is much more square. The kid that was building with the LEGO pieces gets jealous, though his brother allows him to play with his, which excites him. LEGO took Nintendo to court, claiming that it was wrong for Nintendo to compare the two products and that it was plagiarism. Ultimately, LEGO lost the case and Nintendo continued to sell N&B blocks for a short while. In the end, however, LEGO won since Nintendo's products were no where near the same quality, with the blocks often detaching from one another. After a short while Nintendo abandoned the brand, though made mention of it in Super Mario Land 2: 6 Golden Coins in the form of a stage built entirely of N&B Blocks.
