I once played on an Acer laptop. The OS was WinVista Ultimate 64x, with a Core 2 Duo processor and 2 GB of RAM. It lagged terribly during gameplay, even in the main menu. I completed one campaign mission for Haven and one for Stronghold. I noticed that a large part of the functions, artifacts, and similar features are only available online, which is unfair to offline players. Let online play be limited to local networks and the internet, but not the campaign. I started a mission for Inferno, began one of the battles, and when I clicked the "Open Gate" button, the game crashed. It seems that this part was tested even worse than the previous one. After that crash, I abandoned this part and continued playing "Heroes of Might and Magic V" until my previous laptop became completely unusable (now I have a Lenovo). This installment wasn't very successful, do many people agree?
