Well. Interestingly, HoMM5 Gold Edition just dropped to 10 Euro, and since this discussion had just caused me to raise my buying threshold for this game from 5 to 10 Euro, I bought it.
So far it's a bit of a struggle. The factions, hero abilities, town buildings etc. seem nicely done, the amount of content there is satisfying.
But the interface is driving me nuts.
I started in the underworld, and for some reason, the developers thought it would be a great idea to have immense walls and pillars blocking the player's view. They don't even look nice. In HoMM3, the map shows everything I want to see. In HoMM5, I'm so far finding myself cursing the controls because I have to wiggle the camera to even look at some spots of the map (like small alcoves).
There is no clear distinction between buildings. In HoMM3, an ore pit is immediately recognizable since it looks like a big pile of ore. A sawmill has some wood in front of it. Each mine type has its own distinctive coloring and is easily recognizable. In HoMM5, ore pits and sawmills are both brown wooden buildings. I have to zoom and tilt the camera to identify the buildings.
Although the map is more empty than that of HoMM3, it's harder to make out objects. I find myself moving the cursor around my hero, "guessing" whether there might still be a chest or some other object next to him.
The graphics are inexplicably laggy. I have an ATI Radeon HD 5670, i.e. a card that came out several years after the game was released. One would imagine that it's fast enough for the game. Yet, when I start it, I'm looking at a frame rate of perhaps 1 FPS in the menu. I then have to switch the settings to "default" to get fluid movements. Then I have to set things like music volume to my preferred value because it got set to default too. I have to redo this every 4th or 5th time I start the game.
In game, the cursor was lagging to the point of being unusable. The only way to fix this was to switch on the "hardware cursor" setting. The cursor now moves smoothly, but is so small that I have to take guesses as to whether it shows a standing or prancing horse.
Even with all graphics set to the lowest setting (again, this is on an ATI HD 5670), there are some stutters in the graphics (like in the circle moving around the active hero, or in the camera fly-by in towns).
Combat wastes 30% of the screen for "surroundings", and draws the creatures so small that any details on them are lost. I can zoom in, but then I only see a part of the battlefield. Zooming in isn't such a good idea anyway though because the creatures are very primitively done. I don't care much about looks in a strategy game, but it baffles me that amateurish 3d graphics are seen as an improvement over HoMM3's very well-done 2d graphics.
Information isn't available when I need it. My hero has a special ability which causes his Blade Dancers to be "Enraged". What does "being enraged" mean? I have no idea. The hero's screen doesn't explain it. The blade dancers' screen doesn't explain it either. I'm clicking my way through a labyrinth of submenus and still can't find it.
The towns now have a useless 3d look. Again, previously (in HoMM3) I saw everything I needed at a glance. In HoMM5 I don't.
Also, there are tons of submenus, sub-submenus, and sub-sub-submenus, which are all controlled from an UI element that is tucked away in the bottom right corner of the screen. Instead of controlling the UI elements with buttons on the elements themselves, I always have to move to the bottom right of the screen, check what the controls read (they are different for each screen), click the one I want, then go back to the UI element I wanted to look at, click on the tab I want to see (on the far left of the screen), then go to the far right again if I want to navigate to a different screen ... it's madness. All the while, one half of the screen is wasted showing useless graphics, while the info I want is limited to the left half of the screen, split into several tabs which have to be accessed one by one.
Even things that should help the player are infected by design madness. There are apparently two types of tool tips showing information an hero abilities; one showing more and one showing less info. I usually start reading the tooltip, and then, while I'm in the middle of it, it suddenly switches from one format to the other, and I have to search for the sentence I was reading. How is that supposed to help me?
This is by far the least usable UI I've ever seen in a HoMM game. It's as if the devs were being paid for the distance the users have to move the mouse back and forth, and for the time users have to spend to figure map objects out.
Also, turn times are surprisingly long for a franchise that always had quick and primitive AIs. I generated the biggest map available (I always play the biggest maps in my strategy games), and already have to wait 2 minutes for the AIs to make their move - and they don't even have much to calculate.
So far, this has been a disappointment. There might still be a good game underneath the horrible UI, but if I can't find a way to make at least the map objects clear and discernible without continuously having to work the camera, I'm not sure if it's worth looking for it. Are there mods which address these issues?
