I just started Fire Emblem: Awakening a few days ago and... Ugh. The pain.
This is my first Fire Emblem, and I'm on Hard/Classic, since I feel like I should do that at least once in my life. Next Fire Emblem game I play... screw this Classic stuff. I mean, I like a penalty for losing a unit, as long as it's not perma-death. Maybe you should lose HP and stats temporarily each time you go down, and you have to go out of your way to get them back. You know... something that still hurts, but isn't perma-death.
The Exp. and random stat gains are straight out of 1980 as well. Most modern TRPGs I can think of make stat gains more stable, which I think is a good thing - at any level, you know exactly the amount of leveling resources you have, which makes planning easier and doesn't give a player a crappy character because the heart of the dice turned black for two seconds.
And Mission 7 was a god damn pain. I'm somehow enjoying the game despite the outdated design, though. ^_^;
