Finally, a game I can actually see on my GBA! Besides that it is addictive as heck!
At it's core it is so simple! Just ((Unit A * Defensive Position) * Aggressor) vs ((Unit B * Defensive Position)
But add in the story and all the different unit types and terrain features and fuel and ammo consumtion, and you have a great strategy game that you can take anywhere with you. I get almost every GBA game, and this is the only one that I have kept!
