Grading the Sixth and Seventh Console Generations
GameDaily has up an article grading the current and next-gen consoles on their past and (apparently) future performance. Ratings come with an explanation, which is good because some of them seem just a bid dodgey. Only a B+ for the PS2? Really? From the article: "Considering the competition, the PS2's $129.99 price tag seems downright diminutive. The slim PS2 comes sans fan (meaning potential overheating for long-winded players) but the compact design makes it a must-have for anyone with limited space in the entertainment center. The DualShock 2 is arguably one of the best game controllers of all time and extras can be snapped up for a mere $20 for head-to-head or online multiplayer action." The Aeropause blog has a follow up on the ratings, giving you another perspective on the same consoles.
Every Final Fantasy game in the main series except III and XI runs on a slim PS2. Even XIII is for PS2.
