So I'm gonna get a PS2 very soon, at $25 with two controllers, so I wanted to know what are some great games you guys would recommend for me. I'm into RPGs, action, shooters the most but other great games are welcome too!
If you don't mind spicing that RPG up with some Strategy seasoning, pretty much any Nippon Ichi developed title released on the system is worth your time. Of them, I'd say Phantom Brave is my personal favorite (and is also my personal favorite Strategy game), while Disgaea 2 is also great. Soul Nomad and the World Eaters is the most unique of the titles among them and is likely bit like any game you've played before.
On the Action RPG front, I highly recommend .Hack and its sequel G.U...or I would, but those game's are expensive as hell and there's no other system to play them on. Still, if you get the chance, I'd give 'em a look.
As for Turn-Based RPGs...well...Persona 4. If you have a Vita, nevermind, if you don't though, I'd give it a look. The Vita version offers a lot of improvements and additions, and it also adds changes both big and small that make P4 for the PS2 something of a unique experience. And really, in terms of RPGs, you can't go wrong with Shin Megami Tensei, as during this era they had quite a bit to offer. The PS2 Persona series is a lite-Dungeon Crawler crossed with a school/life sim (Though in the case of Persona 3, "lite" would be an understatement, and grinding is your best friend), the Kuzunoha series is basically Shin Megami Tensei's take on Youkai Watch if it was an Action RPG, The Digital Devil Saga games are an interesting return to form for the series with something of a dark reversal as far as protagonist role goes, and Shin Megami Tensei 3: Nocturne, which Spino can vouch for (and has). So there's a lot there to sift through.
