I had the same thoughts, I already owned SH4 Gold but thought I should buy SH3 and add GWX so that I had a dedicated U-Boat sim and a dedicated fleet boat sim. So Amazon was nice enough to sell me an unused copy. As it turns out I was so accustomed to SH4 that SH3 was quite alien to me so now it sits on my hard drive and I use OM with SH4. I just don't have the energy to learn another game when SH4+OM do what I want anyway
