I like order. Not OCD levels of order, but an appreciable amount nonetheless.
I want to play Killzone 2 (PS3).
Killzone (PS2) comes before Killzone 2 (PS3).
I am now playing Killzone (PS2) and am currently on chapter 5. It is not a good game. It is vastly better than the first 30 minutes makes you think it is, but still not a good game. It's hard to believe Sony was willing to stick with this franchise after being kind of embarrassed by their original "Halo-killer." But I hear great things about KZ2, so I will push on and fight the good fight.
It is now beer-thirty. Possibly wine-thirty depending on the company.
