Absolutely loved the PS2. Despite a pretty mediocre first year overall (I imported a system in April 2000 and am counting the time from that period onward), the system ended up becoming my favorite console of the previous generation. I've owned multiple systems over the years, and right now just have a black PS2 slim with a mod chip for imports.
