Welcome to GTPlanet ZondaLM... I think you'll find that the general consensus here is that GT4 is worth a try, otherwise this site should change it's name!
Check out our FAQ's (
here), the GT4 main page (
here) and browse/
search the
forums a bit, and see what your missing. Aside from being the most realistic driving sim around, GT4 has alot more to it than previous incarnations (pardon the pun!) of the game, but also keeps the best parts of the series intact.
For the record, I do know a couple of 'hardcore gamers' who don't play driving games, but since you are already familiar with the series, GT4 won't disappoint (unlike some other games I could mention

) The biggest criticisms levelled at GT4 involve the lack of damage and particularly the easiness/stupidity of the AI, but like previous GT games, it really is as hard as you want it to be... a bit of thought about car selections and set-ups, and GT4 can really give you a battle. Failing that, try taking part in the
Weekly Racing Series here at GTP, where you can pit your wits against some of the fastest guys and girls around...
