Well I have personally met 3 of the developers, and understand the time and pain they have gone through to make this game. I want to support them, as a friend, more than an anonymous company.
Not only that, but Silent Hunter 5 has so much promise, something I wish I could of contributed to, and as such, I'll contribute my part in purchasing SH5 and maybe release a mod or two, to the few people who do go ahead and purchase SH5.
I had dialup until last year, and I would, still purchase SH5 and deal with no phone for hours on time if I had to play. There's always my cell phone
