I mentioned it earlier but I want to highlight a real gem on Gamecube, Metal Arms: Glitch In The System. I don't know if many of ye have played it, I doubt it. It's absolutely brilliant and if you don't like it then you don't like gaming. It crosses so many genres and it's hilarious. Get on Ebay and hunt down a copy now.

It's more like a 9 in my books and is recommended higher by readers of IGN. Same story on Matacritic, 8.3 from critic reviews and 9.3 from readers. It's got Homer Simpson's voice actor, need I say more?
