Slippery Jim is completely right. Which is too bad really. The fanboys you see on BIS's forums makes me sick TBH.

I do like the fixes in this latest patch though (not that I can try them out). Having multiple saves is a good addition as having one save in OFP and ArmA sucked. I just wonder if the HDR implementation is done any better in ArmA 2. In ArmA 1 is was such a horrible implementation.

There was a demo for ArmA 1 but it was a pretty crappy put together one. The ArmA 2 demo, which should be out next week, sounds to be a lot better since it'll be 2GB worth on content. Plus it comes with the editor so it does have a lot more value than every other game's demos at least. Then again, looking at BIS's track record with bugs that may not matter much.
