Probably this is not your thing then.
It's very fast to do, probably 15-20 mins if you know waht to do; however, polycount is not very low. The more details you have the bigger polycount. For games, I think you need to retopo, if you consider this way of modeling.
I have done something to game models and I feel that poly modeling is the way to go there; also, careful UV mapping is a must with low poly models.
For low poly game modeling Blender is very good; Wings3D and Milkshape 3D are good options too. Curvy is more of an artistic tool.
