What would the advantages and disadvantages be for both parties? (Columbia and MARVEL) Not necessarily a complete crossover (although discuss that too) but Easter Eggs and references. In my opinion, with Easter Eggs and references the companies could only benefit since a) no profits need to be shared and b) it can only bring more excitement for both franchises going forward. When comes down to crossovers (Spidey appearing in the Avengers), however, the legal stuff, profit division, etc. may not be worth it unless Spidey is a severely integral part of the story (Civil War). What do you guys think?
