Hey guys,

Word of caution to those looking to pick up PvZ via Steam, seems that a fair few people have had some issues with PvZ deleting its own save games after hours of progress.

It seems to be mainly affecting those who purchased the game prior to a recent patch, so if you're just buying it now you might be unaffected. For what it's worth I got the game via Steam before the patch and I've had no problems. Yet. Fingers crossed.
I'm using Vista 64 bit.
But other than that, if you're even remotely interested in the tower defense genre, get it! =)

Hmm, pretty interesting. I got the demo tonight to see if the game was worth it.
