At a little more than US 30 a pop (on P500), I could afford all three of them at once, with some budgeting elsewhere.
I just couldn't play them at any time anywhere feasibly.
I can pick up any of them on Vassal for free at any time, for example, and two of them (Hunters and SVic) have some very nice ports to TTS. Am I playing them? ha! So what does that tell me?
That tells me that any money I spent on them would be purely out of gratitude to the publishers, devs, and designers; I would never really play them. I have nowhere to play them anyway.
I would be much happier just playing the current Uboat PC attempt (still in development alpha), and/or mod-patched SH3, 4, and/or 5. The latter of which by the way I have never tried to play, although I'm pretty sure I bought them...
