That is the proper description. I played that for years after v1.5 came out, and I was miffed at Ubisoft for charging us money for a "patch", or "fix", and I refused to pay for it... sheesh - what a cry-baby I was...
I still recommend getting the v1.5 update though. You can "subscribe" to products on Amazon, and have them notify you when it goes on sale - I think... Been a while since I tried that. I know you can on Steam, but the Steam version of the update only works with the Steam version of v1.3 SH4 anymore...
