When I asked a family member to guess which town was from official DLC and which from fan mod (Conflux vs Cove) he picked wrong, claiming that Conflux buildings have less polish so it was fanmade. This is the quality we are talking about here. For me, HotA is real continuation of HoMM we never got from original creators.
I love original game. A lot. I play it on wine all the time even after all this time. When i've found out that Enchanced Edition is native for Linux i've immediately jumped for it, waited for first discount and bought it. I knew, that fresh games are bug prone, especially now. But i'm writing it in 2021! It's been over 2 years from premiere! And yet... Game hangs on startup exactly every second startup. And it's not your friend normal "alt+f4 to stop program" hanging. It's "i'm listening to everything you try to do with keyboard, but decide to ignore it". Sending SIGTERM? Who needs that. Without SIGKILL you cant stop this monster. And this is only beginng. Fullscreen is totally broken. That is probably why, developer just removed "fullscreen" option from menu. I'm not joking. This game has no in-game option to change to fullscreen. Official way to do it is by changing configuration file. And then you will find out, that your mouse clicks in different place, than it actually is. This, and many more bugs. 2 years after premiere. And we still did not actually start game... ...And maybe it's better? I've managed to do it, and only thing that awaited me there was more of "your mouse clicks in different place it is", "we blocked print-screen button, so you have more problems requesting refund" and many others. TLDR: Stay away from this dumpster fire. It's horribly broken, expensive and even after that, brings almost nothing over Diamond Edition.
