Just make sure you get the right one, as there’s actually three versions. They released the prequel trilogy and original trilogy as separate games first, then re-released both together (with a few improvements) as Lego Star Wars: The Complete Saga. Unfortunately though, for some reason, it wasn’t released on the PS2, only the current gen consoles. If you have the choice you’re best off going for the complete set, I doubt there’s much difference in price.
Heh. We already got the “Original Trilogy” and really loved it. But our disdain for the prequels is enough of a deterrent for us to stay away from the prequel trilogy.
Hm. Curiousity check. Do the games in question need to be multiplayer? Because the narrows the field a LOT. (Cuts out Okami, more or less strips out Katamari Damacy, though leaves We <3 Katamari.)
Though thinking of the multiplayer game that got the most time on my PS2, I float Tales of the Abyss. You’ll laugh, you’ll cry (it’s better than Cats!) and uh… stuff. Assuming you can get into a character driven JRPG. And assuming you can find a copy, since the only place I’ve seen selling it lately is Amazon, and they’re asking a staggering $93.
If you like arcade-style racing, try Midnight Club 3. Lots of ramps, one of which sends you to a rooftop if hit fast enough!
I’ve enjoyed most of the Need For Speed games, and Need For Speed: Carbon is a great game. The drift racing alone is worth the price, plus the mini games are a lot of fun. Trying to escape the police while driving a dumpster truck is hilarious.
The only drawback: all the racing is at night. It’s well done, but still, it’s always night time.
Evil Genius. You play a stereotypical Bond Villain, build your underground lair (on a volcanic island, of course!), hire and train henchmen and minions, and send them out to do your bidding, whilst battling The Forces Of Justice. It’s bright, fun, and pokes fun at both itself and the entire '60s Spy Film Genre too. 
The best part is that it’s free, at least on PC. (And its graphic requirements are pretty low.) All you have to do is sign up for the free version of GameTap, and you can download it.
On the PS2, you’re looking at $12.99, if you don’t mind refurbished, or $19.99 new, though.
Hello Munch That sounds like it would be a great bargain apart from the air fare required to fly to the States As it happens I did manage to get it fairly cheap-ish so I am a very happy bunny just now, especially…
…as I managed to get the complete version thanks to a really good sales bloke at the store. My cuppetheth runneth overeth.
Thanks btw DC Trekkie
