So I just started playing, thus am not familiar much with the game, but here are some comments that I have so far from the little I played.

1) Making a new character

When you select an ability for your character, the tool tip sticks on the ability you chose and will not update when you select or mouseover other abilities. Specifically, I picked Serpent Pact, I believe it was-- the one that lets you summon drakes and such-- and the tooltips for the other abilities did not update. Even after deselecting the ability I purchased.

2) Of the 3 or so starts to the game I played, 2 of them had me starting off surrounded by monsters far too strong for me to take. My level 1 sovereign was up against things like black widow spiders (that killed me in 2 hits while I would do about 1/4 their HP in damage), ogres and after a little exploration with one of the heroes I hired, even a fire dragon which roflstomped everything. This was all on easy settings (large world, medium monsters, high magic, standard resources if any of those options help. Random map, balanced terrain, too.) ... The third game I started on was a little better, perhaps it was bad luck, but...

3) One of the things I really enjoyed about Master of Magic, were the different units you could summon in addition to hire/train. So far, I see that only 2 schools of magic have summoning spells and they summon the same kinds of creatures. Are there any plans to add special summoning mobs to all the schools?

That's all for now. As I mentioned, I really haven't played much. All three of the games ended fairly abruptly from crashes (Win7, 64 bit) but I cannot really say why. I just got the standard windows program crash box.
