It's going to be the same thing with MK9. When Injustice is at a tournament, most NRS heads will enter, the same way they entered MK9. That counts as playing the game. But if "playing the game" means grinding out match-ups, labbing, etc... then I don't think most will be doing that, because it's not that easy to divide time, especially when most would just prefer to spend their time on the new game given that there's a lot more they don't know about it (irrespective of MK over DC preferences) so it's just more exciting., Every time someone contemplates playing Injustice, they'll realize that they can be practicing MKX instead, which is more rewarding since there's more to learn, more tangible improvement to be had, and tournaments to prepare to. The main problem with playing two games at a time is the opportunity cost. Every time you're playing one, you're not playing the other. So in the end, the majority of your time will be spent playing the one you prefer, which in this case is probably going to be MKX.
