Yeah, I *think* it is only 2 player internet, but I'm having a hard time finding any information on it, actually, so it could be more.
For some reason reviews don't mention the multiplayer for either of these. I'm trying to trade for a copy of GP4, so if I land one, we'll have to try the multiplayer out and see for ourselves.
Got some time in w/ F1 2002 last night, and I think it is incredible - the 'work in progress' demo seems to have been just that - a work in progress. The full version has better graphics, better performance, more detailed tracks... the sense of speed is terrific!
I spent a couple of hours at Monza last night, which was fun because I watched a replay of the Grand Prix of Italy at Monza on Speed TV sunday, and the first chicane IS a brutal sonovasqueak (there's no way you could take it at 71mph, as the graphic at FIA indicates).
VERY fun!
GPL should be here in a day or two (along w/ my new wheel, which didn't arrive yesterday as expected

), so I'll practice up and then you guys can show me a thing or two!
