Ah the Gamecube. A purple little box with a handle so you could easily carry it around. I had some fun times with my little friend. Wind Waker, Ocarina of Time, SSBM, Super Mario Sunshine, but there was one game that made me love First Person Shooters for the rest of time, Time Splitters 2.
I would spend countless hours playing the multi-player mode by myself with the hardest bots on the opposite team, and the most retarded ones(note: Nameless Ted) on my team. I had so much fun running up and down levels playing Capture the Bag for hours on end. I couldn't get enough of it. For an FPS on the Gamecube, the rewards were phenomenal! All of the challenges and characters to unlock kept me going for months on end! The insane difficulty of the single player on hard mode made me want to throw my controller in rage, but I still played them, over, and over, and over.
Speaking of the single player, how about the writing, huh? Fucking outstanding! The only game that has funnier writing, and you all will agree, is Portal. But god, I would laugh and laugh at the cut scenes in between the missions, and then I'd be pumped to kick some major ass afterwards.
An old game which I wish I could still play today, but sadly, I can not. My Gamecube's lid has been glued shut(thanks to how much of a cunt my sister is), and my game was sold many days ago. But I still think about TS2, I still remember the great times I had playing through it over and over and over again. If you can find yourself a copy of it in a bargain bin, pick it up. You can probably find the PS2 version, so grab a copy for about 5 or 6 bucks. You'll enjoy it, I guarantee it.
