We download Heroes 3 HD and go enjoy the great series of Might and Magic, no questions asked.
If there's no way to find something new and put your soul into your project, then there's no point in even starting it.

The fourth installment broke the boundaries established by the series, which is why it failed. And even then, it still found its fans. Of course, many more people will flock to see another clone of the third game; who would argue? It's all about making as much money as possible.

No one is against something new and heartfelt, as long as it's done well. Right now, the seventh game is too raw to understand its strengths and weaknesses. Maybe it will surpass all the previous installments once it's finished...

The boundaries of the series? And how do you create a new game without breaking those boundaries? Too many new features, and you'll get a new fourth game; too few new features, and you'll get an "add-on" to the fifth game.

Essentially, what are new games within the series? Improved graphics and a new story (if the game has a story).
