To all the doomsayers, i say, suit yourselves. I believe time changes, people changes, and games changes (sad but true).
I think it would be important for us to give HoMM5 a chace b4 all the swords are drawn. H4 might have given a lot of ppl bad experience (I dunno why, but i like the game), but i still think that its too early to condem the game now.
I personally feel that we should trust the developers on it (or until they had offically screw up), putting them down right now, even before we played the game, is totally unfair.
Personally, I will give this game a go, with no prejudice nor pre-conception. I will play it as though I had never played any heroes games before, then make up my mind on it. (But I really hope that after such a long time, H5 will live up to the series name.)
