Honestly, PS2 is my least favorite console, despite the massive amount of games. With that said, there are some true gems on there.
Rez: Fucking awesome…for an hour. But man, that hour is how I imagine sex would be…(cries self to sleep) Although the core on-rails shooting gameplay isn’t anything to write home about, the way its blended into the visuals and audios make for one of the most unique experience yet. For you see, there’s a specific “rhythm” to each level – each time you destroy an enemy, a musical note sounds, which ties directly into (surpisingly good) techno soundtrack
Beyond Good and Evil This is perhaps my favorite game of the last generation, and certainly among my top 10 of all time. It offers an epic storyline, along with Zelda-esque gameplay, yet always feels completely fresh and inspired. The pacing is perfect, the graphics are still great, and the game play is top-notch. Play it now.
Need for Speed: Hot Pursuit: Forget about those poser “Underground” spinoffs, this is the real deal. You race exotic cars around while trying to avoid being rammed off the road by the police, who somehow have the budget for equally exotic cruisers. I don’t know if you like racing games or not, but this one certainly leads the pack. Also, I loved the police chatter – some great stuff there.
Metal Gear Solid 3: Subsistence: Yeah, this game isn’t exactly a low-key title, but perhaps you missed it. I’m not a huge fan of the MGS series, but I’ll be damned if this game didn’t humble me. Amazing graphics, stellar story (not so much for the actual plot, but the execution), and one of the most engaging conclusions I have ever experienced (the last two hours are non-stop action). Oh, and the stealth system is actually fucking awesome in this game, between the camouflage system, and the surprisingly good AI (no more 5ft cones of vision here).
