Its really good. Six factions, different game modes like Arena, Classic, Single Hero and Scenarios, plus a campaign. At the moment only campaign Act 1 is available, but that is already 10+ hours. I think there are also hotseat and multiplayer modes. There is a ladder as well which I have not tried yet. Some of the music is really nice and I like the colorful art style. Each faction also has around 18 heroes with different skills.
Each of the factions feels pretty unique and has 7 units . Each of the 7 units has 2 upgraded version with different stats and / or skills.
The game was really hard at release, but they hotfixed that so easy and normal are now doable for noobs like me.
The only thing missing (for me) at the moment is proper team modes and co-op, but that is currently the developers number one priority.
Reviews are very positive at around 89 percent as of writing, and the game seems to have a bright future ahead, with over 500,000 copies sold in just a couple of days. Long-term support is basically guaranteed.
All of this is coming from someone who does not have much nostalgia for the series beyond playing Heroes 5 a bit. Even a lot of the grognards seem to agree that this is the best entry in the series in a very long time
only tangentially related, but M&M ripped. it's a shame it never got the morrowind entry and died out before that, because 6-9 felt pretty similar to daggerfall
