Actually I'm not assuming that at all. I'm not assuming that every casual fan will automatically like the arcade elements. What I'm assuming is that every casual fan wont care about all of the hardcore elements that people on this forum want.
Take Demetrious Johnson. As you know he is the UFC Flyweight Champion. You would expect that someone with his expertise would want a hyper realistic version of the game, right?
That assumption is wrong. He has been quoted as saying he dislikes the stamina in the game and thinks its too taxing. He wants to be able to throw spinning kicks and strikes with no stamina penalty. Now thats counter to what 90% of the forum thinks about this game. Everyone here wants perm stamina to be more taxing than it is.
DJ is an example of some casual gamers. They can appreciate realism and arent going to object if its in the game unless that realism affects their ability to have fun. So if you are trying to appeal solely to "sim" players, you run the risk of losing out on fans like DJ. Their money is worth the same as ours.
Thats why UD3 was perfect for me in some ways. I have no idea what playing UD3 is like without sim mode. I've never played it on arcade stamina. I have no interest in playing it that way. But I'm sure there were thousands of buyers who preferred playing it in arcade mode.
Thats why in favor of having sliders or a sim mode and giving individuals the right to cater the game how they want it.
