Well, since it's not the 3rd installment, it means it's not the 2nd, 1st, or 5th either :D
You see, the title doesn't meet the standards.
We were expecting a "Heroes" game, but we got a game with "Heroes" in the title that isn't really a "Heroes" game.
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 installment?
There's only one explanation: players want to play a "Heroes" game. What's so hard to understand?
And as for the 6th installment, it's so similar to the others, they're practically identical.
