This is, by far, one of the best RPG's ever.
It has great graphics, great variety in terms of weapons, great variety of dialogue & choices and above all, great story-line.
i finishes it twice already and I'm in for a third time now.

Pros:
1. Good graphics;
2. Good effects;
3. Good troop variety;
4. Good faction variety.

Cons:
1. Too few resource types (waay too few);
2. Poor castle concept (even Heroes 2 is better);
3. A bit too easy (AI is somewhat dumb).

All-in-all, if you want a good Heroes, stick to Heroes II, Heroes III and Heroes V. I for one just purchased this game so I'd have the entire Heroes collection under my belt.
