i just purchased all 3 using the game rush "trade 3 really crappy used games, get 1 new crappy used game" deal
call of duty - just got it today, was too busy watching my beloved steelers to play it yet
goldeneye - better than reviewed so far, the weapons i think are pretty cool, otherwise it is a fairly run-of-the-mill fps that i think has appeal for people who love that genre (a good comparison is xiii for me in that the gameplay was average but i liked it anyway)
nfsu2 - never really played the first, the new one is fun, the city is really cool looking in that, unlike say gta:sa or mc2, even though you drive at night you feel like you can see everything thanks to ample miami/las vegas type lighting, big problem - the game seems dangerously glitchy in that it feels like you can get stuck in a spot in the game with nowhere to go, i have already been asked to do things with a car i am not driving and have won races without getting payment, another negative is that there are so many quality race games (b3:t, pgr2, rs2, mgp2) it is hard to justify a fat purchase
my bottom line: they aren't bad but i'd wait til you can get them really cheap
