changing the engine means nothing if they still build a bad game with it. that refers to WWE and NHL
Sure.
WWE's issue is they aren't putting enough focus on any certain thing. They go halfway with MyCareer, halfway with online play, halfway with Universe. Instead of going for full boost to say, MyCareer, and then minor improvements to all the other areas.
NHL's issue is that they have blinders on. They are all about HUT every single year. EASHL gets some touch ups, while Be A Pro, and Franchise Mode are left sitting there with minimal changes. Be A Pro shouldn't even be in the game because its just nothing.
However, with the engine, it's pure gameplay, and while both have their warts, both are pretty solid IMO. NHL's engine is just severely outdated, and Frostbite will make everything look better, and run smoother, and increase what can be done. So it'll make it better.
