Okay so I've been seeing threads of people complaining about a fair share things. The two largest complaints are the lack of enemy database thing, and the difficulty(from what I've read here, so pls go away Discord comments). SO I'm to share my opinions on these complaint and so and so fourth.
Enemy Database
So it has been stated here will not be an enemy database, which several people are upset. My takeaway is while database would be nice(especially for wiki stuff) it isn't necessary for this game genre. If you play any RTS game, you rarely get info about your troops, let alone your enemies. The fact that they have pop-ups telling us about the enemies is a luxury in of its self for this genre of game. "But how do you plan for the levels ahead of time". You don't. You plan in "Real-Time", thus the name RTS. You have to adapt to the situation in the moment, which segways into the next topic.
Difficulty
RTS games are notorious for there demand in skill level. Players have to have extraordinary micro-management skills, and reaction time. It's this reason why game in this genre are so difficult or high skill. StarCraft(1&2), Total War, Command & Conquer, Halo Wars 2(1 was easy imo), and Warcraft were all very high skill games. While IM isn't quite on that level of difficulty, it still requires these skills. You have to be able to assess your situation and adapt accordingly, which they make far easier than a normal RTS. As result if you little experience with RTS games, or don't play games that don't utilize the skill above then Yes, this game will hard for you. Personally, I only had trouble with 2 levels, The one before the Fell boss, and the Spec Ops mission with the sentry turret(Cause micro is hard).
So in conclusion while KR and IM where made by the same company, you can't really compare the games to each other. There very different gameplay-wise. KR is far more plan ahead, and make small adjustments along the way, which made the game hard for me because I fit more into the IM playstyle, which is plan in the moment, adapt to your situation. However there is on thing that both games share that eventually make the game easier, and that is Trial and Error. To anyone having trouble try different strategies or playstyles.(I will give a hint though, the Rangers paired with Diplomats are really good against the Fell, and throughout most the game)
Not to mention this the first non tower-defense game IH have done, so there are gonna be a few mistakes or quirks that we aren't going to like.
Overall I enjoy the game, but I did find it extremely easy to beat, but that's just me.
P.S Sorry for semi-douche-baggish title
