I realize this is one of those 'now that I've said it, it's going to happen' things, but I've put close to 9-10 hours into Ghost Recon since launch and haven't had a crash yet. Anecdotal evidence and all, but I figured it's worth pointing out that not everyone has had an issue.
Love the game... glad it was a launch title, frankly, since I think it'd would've easily been overlooked had it been released any other time (or on the DS).
