User blog comment:David eric/Third-Party DLC characters?/@comment-24357950-20150403204732

Well... you see, the SSB series is very very popular dear. A character representing his/her game in Smash Bros often leads, just as it did with Fire Emblem, to an extreme influx of demand for that game the character came from. Therefore I think barely any gaming company, whose games fit into the SSB theme, would refuse to let a representative of one of their games appear in SSB. So if a certain third-party character was voted for very very often and the producers of SSB see that there's a huge demand for that character, I am certain they will do their best to get the rights for that character. And for the reasons I stated above, I think they would have, in most cases, a good chance of succeeding there as well. However, getting the rights to add a third-party character is very costly. So consequently, if the demand is not extremely high, they will go with a character they already have the required rights for. If the demand, however, is extremely high, they would add that third-party character and it wouldn't be much of a problem to buy the rights for that character.
