Advance Wars. And there's a way to tone the difficulty down, it's called don't buy Hard Campaign. It wouldn't be too hard since the campaign seemed easier than it was in AW1 and 2. It took me a couple of tries to beat the final battle in the first one (The battle with Eagle at the very end was hard too), I couldn't finish Green Earth before my gameboy got stolen in AW2, but I actually beat the last mission of the first try in this one. Than again, Hawke and Lash are really good COs and Von Bolt sucks. Anyway, I still think it's the easiest AW. Most of the War Room maps have been changed to allow you to stay on top. Like the extra base on Spann Island where there was once a city or owning one of the farther up bases in Land's End.
