Timesplitters 2 was better than the first, and Future Perfect better than that, IMO. Each MGS gets better too (let's not include the iphone game or the psp games (though I liked em) and just say MGS 1-4. Each one improved on what the first had started. Espionage, stealth, and conspiracy and such. Killzone easily got better. I liked the first, but it did have it's problems. Even if you were the guy that said "LOL FAIL Killzone isn't the Halo killer!" you can't deny that Killzone 2 fixed everything from the first and then turned the dial to 11.
