Street Fighter. Ever since Street Fighter 2 it has been my all time favourite gaming franchise. But thats not to say other games havent come close. Guilty Gear X2 is smurfing brilliant, but to surpass Street Fighter III 3rd Strike is a difficult task. As for 3D fighting, I have said Tekken is my favourite 3D fighter for a long time, and I guess it still is. But Virtua Fighter 5 is just so great it could all change.
