Being honest, I did have it on a fairly low difficulty level.
To be fair, I turn the monster difficulty level all the way down to "Novice", with the caveat that I also increase their numbers. (I find it's a lot easier -- and more fun -- to level up my heroes this way.) When I play on the "Challenging" difficulty level, it only applies to the AI players (the other Kingdoms & Empires).
Damnit! You guys are going to force me to reinstall, aren't you? Play another game, aren't you? No wonder I have such a backlog of never-played Steam games
So have you started playing again yet?
Are there future plans for MP?
Not that I'm aware of. Pity really, because it would make a good MP game. I wonder if Punk Wars will be MP, 'coz we like a bit 'o steampunk don't we? Yes, we do.
FE:LH will never have MP, unfortunately; the architecture for it was never built into the game. I agree it would have been fantastic if it had been included, though.
