Hotrod is worth every penny. Imagine you could buy a real arcade machine, instead you get dozens.(posted 8977 days ago)8 way games are great, and there are plenty of those.
Buttons are REALLY good, allowing you to time firing, jumping etc very accurately, not to mention enjoyment with sportsgames like T&F.
Even in a static shoot them up game like Galaga or Phoenix, it helps you a lot.
Only downfall is 4 way games, playing them is not perfect, but better than keyboard.
Or you might want to buy an "ozstick" for 100 Australian bucks. I dunno how good it is. http://home.iprimus.com.au/ozstick/
