I started playing AW earlier this week and been enjoying it so far. Never played a Fire Emblem game but I've been meaning to get into the series for the longest time because of the waifus.
I do like how the units in AW have roles pretty similar to what they do in real life, I didn't expect a cute-looking turn-based tactics game to be that militarily accurate. It does feel like there was a sudden difficulty spike after the tutorial and the first few levels though it's nice having a tactics game that actually makes me use my brain instead of just hoping for good RNG or grinding for stronger units. But for some levels it seems like there's just an "intended" strategy that you're supposed to use to trivialize it instead of giving the player flexibility.
