I gave the Gcube a 4. The Gamecube came out with amazing titles like SSBM, WW, Super Mario Sunshine, Prime and Echoes, and other games. It just didnt have the graphics (and dvd player) of the PS2 and it didnt have the power of the Xbox. While great games came out regardless, it was still last, powerhouse wise, and it didn't bring too many things the other consoles had (Im not talking specific games or franchises here, I mean controls, games, features, etc.)
Still, I chose a Gcube. Despite all its hardware shortcomings, it has some stellar titles. Its no mistake that 3 of the top 20 highest rated games are Gcube titles (gamerankings.com). While I respect the PS2 for Rachet and Jak, and I respect Xbox for Halo and KOTOR, I have to give my favorite gameing experience to the Gamecube.
But now I love the wii. =D
