umm I remember buying the regular xbox with Halo. The Halo copy was used I returned it in 3 days. Then bought Mechassault. I completed the game. I sold everything including the Xbox within 2 months.
I bought PS3 with Metal Gear 4 and Ratchet and Klank. Completed both and sold it within 6 month.
Xbox 360 I kept for like a year. Then sold it. I still have the Wii there.
*Now wondering how am I going to play GTA 5. My beefy PC is crying.
