Right from the start this game has been marketed as a 'kids' game, that advertises/supports upcoming Disney franchises such as Frozen, Big Hero 6 and Inside Out. I've recently noticed that a huge majority of Infinity's fanbase are Adults. Parents play with their kids, or Adults just like the nostalgia factor.
Nostalgia is a huge money making tactic so when 4.0 comes out I'd like to see better support for their Adult fanbase. Less focus on modern characters and more focus on classic old school characters. Cater for everyone haha.
If kids don't know who the character is that shouldn't stop them enjoying their movesets. We'd have a similar problem If modern shows like Gravity Falls get characters.. Adults might not know them :S
Another thing is if they like supporting new shows/movies, why not Daredevil??? I know due to the violence of the show we probably won't see him as a figure anytime soon, but Daredevil could easily be a kid friendly character (he's not gonna add blood and gore to the game, nor swear, he would basically be a two sticked version of Mulan haha). All they'd have to do is put a big red caution sticker on the box (may not be appropriate for younger players). It would make more Adults watch the show (that means MORE MONEY!!!).
It's like the big R18+ games debate we have in Australia, it's the parents responsibility to protect their kids from the violence, sex and drugs of R18+ media. Buying a Darevdevil figure won't instantly turn kids violent -_-
Season 2 of Daredevil will have the Punisher, again I think you could easily make him a fun kid friendly character, the Lone Ranger uses guns :/ .
Anyways better stop babbling on haha! ... What do you guys think? do you want a bigger focus on older characters and less new ips...
