You still haven't told me what's wrong with the fifth game. Besides shouting "I'll only play the third one," "The fifth one is ****," etc. I haven't heard anything from you. That's not very serious.
P.S. What specifically convincing have you provided to prove that the fifth game is so much better that it's no longer interesting to play Heroes 3?
If you're trying to emphasize the quality of the graphics or simply your IMHO against my IMHO or the IMHO of any forum user, then it sounds unconvincing. Moreover, even if the third game were worse, that's no reason to forget about it. I hope you also understand the essence of the question, that "we are not choosing the best of the parts!"
