It sticking around isn't necessarily a bad thing in the case of cover system, and it doesn't inherently mean they just want the Gears money.The problem is not most of them working improperly. The problem is that they stuck around way too long and didn't bring much new to the gaming sphere. That is the major issue at heart, and that so many publishers or devs were trying to get the COD/Gears money and many failed taking unnecessary risks. With most of them learning nothing.
I mean I don't know how I can play a game like Mass Effect Trilogy without cover or GTA/Red Dead games.
