The demo didn't really do it for me, but an F1 mod would certainly get my attention. (Coming down those sweeping downhill left-handers, including getting your wheels off the ground is exciting!)Live for Speed was nice, but I'll have to check out the mods for it to see if I want to purchase it. I'm currently doing a race weekend at Mosport, and having a blast. I've been downloading tracks for it like a madman, have over 100 now, and counting (I'm going to throw them all on a DVD once I collect them all). Debating purchasing it.GTR, well, it's my current favorite. Physics seemed pretty good, you really need to have a good setup and not over drive your car. It's online only, but you can host your own game with a password and throw in some AI guys to test it out without pissing off other real people. Try the demo on their download page.Same as above only Legends version - coming in oct but the demo is out now.This one just came out - I believe it is from the original developers of EA's F1 series (ISI). Little steeper specs than LFS but a great game. Fully licensed and online racing with a big following. You can also just buy the game online so no trip to the store is needed.GTR is not going to cure an F1 fix but it is built on the F1 Challenge game engine. Not a bad game at all and pretty smooth online. No licensed cars/tracks but the mod community backing this game already has a full f1 grid to download.

Most have demos so give them a try.Pretty low specs and a free demo available. There are a few other games out now that are pretty good and have a much better online component (if that is what you want). Either way, if you want online racing look elsewhere.With FIA having sold F1 out to Sony console exclusivity you might have a hard time finding either of these two titles. It also looks prettier and the huge mod community behind it will keep it fresh when the newness wears off.F1C has pretty crappy online play but that is better than none I guess - which is what I recall GP4 having. I also enjoyed the overall F1 weekend immersion and the damage in GP4.F1C also has better physics and ff. F1 Challenge is quite a few years newer than GP4 so it will probably be a little more taxing on your system.GP4 is not the better looking or handling of the two but it does have better AI imho. F1 99-02 is also pretty good from what I've heard, so hopefully someone else can chime in with their opinions on it. Plus it runs like a champ on my PC (P4 2.4, ATI 9800 Pro, 1280x1024, graphics turned all the way up). Solid AI, lots of tuning options, nice looking tracks, and weather that varies along the length of the track. I've always liked Geoff Crammonds racing games, and GP4 is the best of the bunch. I don't have F1 Challenge 99-02 on my PC (I do have it on PS2), but I do have Grand Prix 4.
