I have a question about advance wars 1+2 reboot camp

Ok, so I got the game yesterday as a gift because based on what I saw from the directs it looked cool. I’m a fan of fire emblem and rpgs so I thought I’d like it. Well I’ve made it 10% into the main campaign of the first game and so far I’m not really enjoying it, the fuel and ammo system is annoying, I don’t like how the damage scales on health, there aren’t any unique units (yet anyway), there’s no player choice on what units go where before starting the map (which I feel would make sense to have In a strategy game about war), and everything just feels so slow. I’m gonna give the game another chance today but I’ve gotta ask, does it get any better? Cause I really don’t wanna ask to return it because it was a gift and I don’t wanna seem ungrateful.
