Query: Too big and not durable enough

The Astro Pad is a big controller, especially when compared to controllers on other systems...but the main problem lies with durability. With time one can become accustomed to the feel of the controller, but both the pad and the analog stick break within a few months of playing. This may not be a big issue if you are only a casual game player, but for those who need a durable controller that will endure the rigorous play style of 2D fighting games such as Marvel Vs. Capcom or Street Fighter 3 will be sorely disappointed. Unless you desperately need a Dreamcast replacement controller, I can't recommend the Astro Pad.
