I know that. It's probably happening because Disney no longer wants to support a 4-year old game that has limited earning potential for them (i.e. no download fees) and likely keeps players from joining any of their newer games. Almost have to wonder if the failures of MAA Tactics and MAA 2 played a big role in them just cancelling every MAA game on every platform. It's almost like they think that if there's no more Marvel game like MAA for a bit, then players will come rushing right back to get their Marvel fix if a new one comes out in the future. They likely won't because of how poorly MAA has been supported since Disney bought Playdom in 2014.
And you wonder why people don't think much of Disney's gaming division? This is exactly why. Sucks that Marvel's name is being driven through the mud now by being associated with Disney Interactive's poor track record of running online games.
