Uhh how was it ported really badly? The game had me hooked for like 30hours, prior to when my savegames were corrupted(which is probably the bug you mean).
Yep, that is exactly the bug, but it wont just corrupt your save files, it will also eventually start crashing the game, and then eventually prevent it from running at all.
And it was a stupid little oversight that caused it, a simple logfile that is added to every time you play, and which grows uncontrollably untill it makes the game unstable, it took users all of 10 minutes to come up with a fix, a simple Batch file that deletes that stupid logfile every time you launch the game, so simple, and yet Atari/Eden coulden't be bothered putting it in a micro patch? it could not have taken more than an houer to rewrite the exe to delete that log on launch and release it as a patch, but they just haven't bothered..
But that's hardly the only problem, the game is poorly optimized for many vid-cards, it's pretty interesting that the game will run great on a low end 7 series GeForce, but is allmost unplayable on a high-end 8 series, and nothing was ever done about that, and many other bugs plague it, like digital gauges not working on the PC, and the directional sound system barely working at all, in many cars you can't hear anything if you look backwards, and many other car sounds are badly distorted, and a host of other issues that only exist on the PC version.
It was a very good game, we can agree on that much, but it was a bad PC port, ripe with problems that Atari/Eden has not bothered to fix, ergo, i dare say their track record with their PC ports warrents caution (but if you own a Console, just get it for that instead, as i'm sure it will be a fun game for 360/PS3).
