Revolutionary games require revolutionary game designs and code
Add into the fact that the PS2 has a steep learning curve the 1st gen games we\'re pretty much Last gen games with graphic upgrades and minor power tweaks.
On the other hand games like Starfighter, ZOE, MGS2 Demo, Timesplitters, SSX, Smuggglers Run all have next qualitites beyong graphics with either huge enviroments, large amounts of enemies on screen at once, or 4 player split screen mode running at 60FPS, or in MGS2 which is just mind boggling next gen goodness already
Then games like ,Getaway, Dropship, Herdy Gerdy, Red Faction, and quite a few more are all looking next gen worthy and coming soon
