Breja: Is that really a bad thing though? I think HoMM 3 could go overboard at times. In some scenarios it could really be a matter of getting the right spells when you need them, or starting over.
I do agree about the art direction certainly. Honestly, upon replaying the series now I found myself liking HoMM 2 more than 3, mostly for that exact reason.
And since we're recommending Disciples 2, I feel obliged to point out that the first game was nothing to sneeze at either.
Well, I'm not sure. Some of the levels, especially HoMM3's levels were real battles for me to finish. I remember Gem's scenario took me an entire weekend to beat, or more even. However, finally getting through such a level was always an incredible feeling, and I have to say I miss that a bit in D2. In part I think because there are a couple of pretty OP things you can do D2. That's not to say D2 can't be pleasantly difficult though. It's just that those real monsters of levels in HoMM3 do not have D2 equivalents, at least not in D2's sagas.
Whether HoMM3 difficulty can be a bit unfair / excessive? I have to say I can't really remember this being the case. True that certain heroes with certain spells can make the first level of a scenario much, much easier. But usually it shouldn't be a problem from the 2nd level onwards? I mean it should be possible in the later stages of each 1st level of a scenario to fully upgrade all the towns' mage guilds and have all heroes you want to take to the next level learn those spells.
Damn I should stop talking about this, I'm worryingly close to downloading one/both games!
By the way, just in terms of difficulty, the first Age of Wonders is frustratingly close to being perfect for me. If only those blasted heroes didn't become demi-gods mid/late game. At least it's not a problem in the first few levels.
