Well then play this. It's great and adressess some of the issues I had with HoM&M - offensive magic is useful regardless of how long the game takes, and the max number of soldiers in a stack is limited, so there's no army of 99999 archangels walking over your kingdom. Other than that it's good to rub that HoM&M itch you might have.
35 hours - that was the lenght opf my first playthrough. I did it in 3 or 4 days and sat in silence as the credits rolled. From a mechanical standopint the game is prety good and I found few niggles that spoiled an otherwise perfectly good expierience. They will not affect the score as I cannot seem to remember them, prving they weren't much of a big deal. The completionist in me suffered a bit since some options that are no longer available linger in one part of the menu which is a bit of an annoyance. The mechanic of red and white checks seems like a good idea since if you really need to you can just save-spam something. On the other hand if you don't you can get stuck with no way to proceed at one or two points in the game. As a person who saves diligently and on multiple saves this was not an issue but otherwise... not sure. There is no combat mechanic to speek of. Just checks and your decisions and the game gives you just enough to slip foward and different skill compositions give you alternate options of both means of proceeding with the plot and flavour text. It's a bit of a trip this one. You feel as if you're grasping bit's of a greater whole as you are suspended in a hole of unknown. The feeling is reminiscent of the wah I felt when I played Planescape: Torment but more intense. You feel more detached from the world while suffering from it's limitations. The atmosphere is thick and depressing at many points. Desolation and broken dreams litter the ground wherever you go. If you are into that kind of stuff (as I am) this game is a gold mine. The game might not be perfect but it's damn close and If you are into narrative driven games this one is a must.
