Pretty sure this isn't 'from other games' but here's some small things that I'd change. I have more ideas but they fall more in a 'revamp/rework' of game mechanics 1. Make styles usable by all characters on the account, but only give them the feat for the style if that character completes the collection. Think of it as borrowing it. This makes it more fun to activly hunt the styles down for the costumes. 2. Keep briefings and investigations and ongoing collections character specific, but make completed collections acount wide. This makes it so that people would not need to keep doing the RNG over and over again, but still leaves somethings to go after to collect in the game map. 3. Make heroes and villains capable of cooperating. Someone already mentioned it, but I personally find it a very neat idea to have your character's reputation be the deciding factor if you are a hero or villain. You could start out with a boost based on your choice of mentor. There would have to be only 2 factions for this though. Do something for the sentinels and you'll gain hero rep and such. You wouldn't be able to go from Super hero to super villain, just villain or vice versa after one cycle (think of it as them keeping you a bit on a leash incase of double agent). While it doens't make complete sense in-game, it does give us more options for roleplay. There could also be certain protection detail missions for heroes to do, wich guarantees income but only gives exp if you stop crime. And villains could get heist missions wich guarantees exp but they have to earn the loot. Maybe a bit of PvP with signing up for a patrol and a villain does a heist or something.
