Löve has only one limit - it's 2D. Other than that, you can use build anything you want, in simple and cross-platform way. Löve is easy in terms of API size and tooling, but it's more low-level than other engines and therefore aimed at developers that like to build their own tools along the way. It feels very liberating and productive, plus you are not stuck with sub-par editors (unless you make them such).
