If you don’t own Black Panther Pursuit or any of the sets that included Captain America, I guess it would a plus getting the both of them in this set but Super Heroes collectors tend to be completionists, so I think that scenario will be particularly rare. I guess you could always sell your spares on the secondary market, but really, who wants to do that?
Lego Games launched in 2009, was a series of Lego-themed board games designed by Cephas Howard and Reiner Knizia in which the players usually build the playing board out of Lego bricks and then play with Lego-style players. Examples of the games include "Minotaurus", in which players roll dice to move characters within a brick-build labyrinth, "Creationary", in which players must build something which appears on a card, or "Ramses Pyramid", in which players collect gems and climb up a customisable pyramid. Like many board games, the games use dice. In Lego Games, the dice are Lego, with Lego squares with symbols on Lego studs on the dice, surrounded by rubber. The games vary from simple to complex, some are similar to "traditional" board games, while others are completely different.
The definitive shape of the Lego bricks, with the inner tubes, was patented by the Lego Group in 1958. Several competitors have attempted to take advantage of Lego's popularity by producing blocks of similar dimensions, and advertising them as being compatible with Lego bricks. In 2002, Lego sued the CoCo Toy Company in Beijing for copyright infringement over its "Coko bricks" product. CoCo was ordered to cease manufacture of the products, publish a formal apology and pay damages. Lego sued the English company Best-Lock Construction Toys in German courts in 2004 and 2009; the Federal Patent Court of Germany denied Lego trademark protection for the shape of its bricks for the latter case. In 2005, the Lego Company sued Canadian company Mega Bloks for trademark violation, but the Supreme Court of Canada upheld Mega Bloks' rights to sell their product. In 2010, the European Court of Justice ruled that the eight-peg design of the original Lego brick "merely performs a technical function [and] cannot be registered as a trademark."
Since around 2000, the Lego Group has been promoting "Lego Serious Play", a form of business consultancy fostering creative thinking, in which team members build metaphors of their organizational identities and experiences using Lego bricks. Participants work through imaginary scenarios using visual three-dimensional Lego constructions, imaginatively exploring possibilities in a serious form of play.
