WIth a new generation upon us, I just wanted to see what games have made you guys say I need to buy that console or get you to cave in after a while or even, for the PC, which pushed you to upgrade that old graphics card or overhaul your whole rig? I have so many memories of just having that one game that pushed me to spend more than just the $50 bucks for the game.
N64 - GoldenEye 007. Spent so much time asking my parents for it and was the only game I had for a year.
Gamecube - Rogue Squadron II, looked absolutely beautiful.
PS2 - Soul Reaver 2. Actually I was happy with my Dreamcast, even after they killed it off, but found out Soul Reaver 2 got cancelled for it and had to get the PS2 to play it.
PS3 - Killzone 2. I thought it looked so good in previews and just had to jump in. Was very disappointed and ended up with nothing to play on my new PS3 until Uncharted 2 came out later that year.
PC - actually got a graphics card for the first time because of Half Life 2. A crappy FX5200 but whatevers.
Surprisingly I bought an Xbox 360 not for any game at launch, but because I just liked all the improvements to Xbox Live. Didn't feel like I got that it game until Oblivion came out 5 months after launch.
