Still play RE:4, RE:CODE VERONICA, FF 12,DRAGON QUEST 8, GRAND TURISMO 4. I still play ps1 games

I own all three current generation consoles, and all three 6th generation consoles, but the PS2 still sees plenty of action
Currently I'm playing:
Twisted Metal: Black
Rez
Katamari Damacy
Kingdom Hearts
Xenosaga

Mortal Kombat: Deception Wasn't A Big Fan of Armageddon's Fatality System
God of War
Hitman Blood Money (wasn't excellent but I still enjoy it occasionally)
GTA San Andreas And Vice City, I Like Having My Aeroplanes which the 4th one lacked
Metal Gear Solid 3 (2 wasn't as good with Raiden :'( )

- Pro Evolution Soccer 6 & 2008. Also a quick timekiller when you have mates around. And some tournaments off course.
- Bully. I like the Rockstar games, but Bully is the best. It oozes charm, has a brilliant setting and it's funny to beat girls, nerds, girlie nerds, jocks, snobs, teachers, etc. etc.
- Steambot Chronicles, because it's the best PS2 game.

Any many others one and off, but these 4 are regulars.

Silent Hill 2/3
some of the GTA III Series
some Yu-Gi-Oh games.
Lego Star Wars

That's it.

Right now I'm playing through Spiderman 2 again.

Ahh, the joy of a quality game based on a film.

God of War is absolutely incredible.

The Rachet and Clank games.
Resident evil series, yes, series, can't remeber off the top of my head
which the first one on ps2 was.
Kingdom hearts 1&2
God of war 1&2
Guitarooman
Silent hill series.

Def Jam: Fight For NY is probably most revisitable title on the PS2.

I'd also toss in Metal Gear Solid 3: Snake Eater.

Guitar Hero (the original)
Everything or Nothing
Dragon Quest VIII
Final Fantasy XII

Also I forgot to say Resident Evil 4.

Kingdom Hearts 2
