Maybe I'll be very original, but I'll still ask: what exactly don't you like about the 4th part of the game? Besides the fact that "it's not the third one."
You see, the title doesn't meet the standards.
We were waiting for heroes, but we got something that's not heroes, with the title "Heroes."
It's a good game, of course, but there are some unpleasant moments, like it feels a bit "unfinished," right?
But haven't you noticed that the game is completely different, even compared to the 5th part?
There's only one explanation: players want to play a game that's truly "Heroes." What's so hard to understand?
